- CVE-2026-53209HIGH 7.8
A vulnerability exists in the Linux kernel's Bluetooth advertising subsystem where a buffer overflow can occur when the system attempts to prepend Broadcast Announcement service data to an already-full advertising payload. The kernel fails to validate that the combined data will fit within available memory before attempting the operation, potentially allowing a local user with sufficient privileges to trigger a crash or execute code with elevated permissions. The fix adds a validation check to reject oversized combinations before the unsafe copy operation occurs.
- CVE-2026-55693HIGH 7.8
Vim, the widely-used command-line text editor, contains a vulnerability in how it processes spell-check files. When a user loads a specially crafted spell file (with .spl or .sug extension) to enable spell suggestions, the editor's word-counting function descends through a data structure without properly validating its depth. This causes the function to write data beyond the boundaries of fixed-size memory buffers, corrupting Vim's execution state and crashing the application. The vulnerability requires user interaction—specifically, loading a malicious spell file—but no special privileges are needed, and the crafted files are straightforward to create.
- CVE-2026-57260HIGH 7.8
CVE-2026-57260 is a memory safety vulnerability in Foxit PDF Editor and Reader that can be triggered when opening a specially crafted PDF file containing a malformed Unity 3D object. The application misinterprets data within the abnormal object as a valid memory pointer and attempts to use it, leading to a crash. An attacker could exploit this by distributing a malicious PDF that causes the application to crash when opened by a user, or potentially achieve more severe outcomes depending on how the pointer dereference is handled at runtime.
- CVE-2026-57455HIGH 7.8
Vim versions before 9.2.0698 contain a stack buffer overflow in spell-checking functionality. When processing words longer than Vim's internal buffer limit (MAXWLEN) with certain spell file configurations, the editor writes data beyond allocated memory, corrupting the program's call stack and causing a crash. An attacker can trigger this by crafting a malicious spell file or providing oversized words during spell-checking operations, though the immediate impact is denial of service rather than code execution.
- CVE-2026-6676HIGH 7.8
Avira Antivirus contains a memory corruption flaw in its scan engine that triggers when processing specially crafted tar archive files. An attacker who can get a user to scan a malicious tar file can exploit this to either run arbitrary code on the system with the victim's privileges or crash the antivirus engine, disabling active protection.

- CVE-2026-8357HIGH 7.8
LibreOffice Calc has a critical flaw in how it processes spreadsheet formulas when opening files. The vulnerability occurs because the application allocates a buffer one element too small to handle extremely long, deeply nested formulas composed of many opening tokens. When such a formula is compiled, it writes past the buffer's boundary, corrupting adjacent memory. This heap buffer overflow can allow attackers to execute arbitrary code simply by convincing a user to open a malicious spreadsheet file.
- CVE-2026-46123HIGH 7.7
A vulnerability in the Linux kernel's Bluetooth virtio backend driver allows a malicious or buggy virtual device to expose uninitialized kernel memory to unprivileged processes. The driver fails to properly validate the length of data reported by the virtual device, permitting reads beyond the intended 1000-byte receive buffer. An attacker with the ability to control a virtio Bluetooth backend—such as a compromised hypervisor or malicious VM—can leak sensitive kernel heap data or trigger denial of service. This is a local attack requiring some form of device emulation control, but it directly compromises memory isolation guarantees in virtualized environments.
- CVE-2026-5068HIGH 7.6
A vulnerability in Zephyr's Bluetooth host stack allows a nearby attacker to crash devices or corrupt memory by sending specially crafted Bluetooth Low Energy (BLE) packets. The flaw occurs when applications enable a feature called segmentation for handling large BLE messages, but configure their memory pools with insufficient space to track incoming data. An attacker within BLE range (typically 10–240 meters depending on device and antenna) can exploit this without any authentication, causing the device to crash or potentially enabling further compromise through heap corruption.
- CVE-2026-7831HIGH 7.6
UltraVNC viewer versions up to 1.8.2.2 contain a stack buffer overflow vulnerability triggered when connecting to a malicious VNC server. The flaw occurs in how the viewer processes the server's desktop name during the initial connection handshake. If a server advertises a desktop name exactly 2024 bytes long, the viewer's buffer handling code writes a null terminator one byte beyond its allocated stack buffer. On systems without stack protection, this single-byte overflow can corrupt adjacent data; on systems with stack canary protection enabled, the corrupted canary causes the viewer to crash. An attacker must trick a user into connecting to their malicious VNC server to trigger the vulnerability.
- CVE-2026-0288HIGH 7.5
Palo Alto Networks PAN-OS contains multiple buffer overflow flaws in the User-ID Terminal Server Agent (TSA) component that can be exploited over the network without authentication. An attacker can send malformed network traffic to trigger a denial of service or potentially run arbitrary code on affected firewalls.

The vulnerability does not enable data modification or system crashes.
- CVE-2026-12844HIGH 7.5
List::Util::XS, a Perl module used to optimize list processing operations, contains a critical memory safety flaw in its pairwise() function. When the function processes pairs of values, it allocates memory to store results but fails to allocate enough space if a single block invocation returns a large amount of data. Specifically, the memory allocation strategy grows by only four times the current size in one step, but if a block returns more than that, the function writes beyond the allocated buffer, corrupting heap memory. Any application using pairwise() with a block that can produce large outputs in a single call is at risk of denial of service or potential code execution.
- CVE-2026-20458HIGH 7.5
A memory corruption flaw in cellular modems could allow an attacker to gain elevated system privileges if a device connects to a malicious base station the attacker controls. The vulnerability requires the attacker to operate or compromise a base station, but once a user's phone or modem connects to it, no further interaction or special privileges are needed to exploit the flaw. This is a serious risk for any organization with field personnel or devices that roam across cellular networks.

- CVE-2026-7829HIGH 7.2
UltraVNC Repeater versions up to 1.8.2.2 contain a stack-based buffer overflow in the settings parser used by the web-based admin interface. When an authenticated administrator configures allow/deny rules with unusually long tokens, the application writes a null terminator past the end of its internal buffer, overwriting adjacent stack memory. An attacker with admin credentials can exploit this to execute arbitrary code on the repeater machine. While direct admin access is normally required, this risk is amplified if an organization has been exposed to the related default-credentials vulnerability (CVE-2026-7839).
- CVE-2026-10641HIGH 7.1
A vulnerability in Zephyr's Bluetooth Classic implementation allows a remote device to crash or corrupt memory on systems running vulnerable builds. When a Zephyr device establishes a Bluetooth connection using the Hands-Free Profile, it expects responses from the remote device that follow a defined format. An attacker controlling or spoofing the remote device can send a malformed response with an unusually long list of indicators, bypassing safety checks and writing data into unintended memory locations. This memory corruption can disable Bluetooth functionality and potentially affect system stability. The vulnerability requires the attacker to be within Bluetooth range and does not require user interaction to trigger.
- CVE-2026-10658HIGH 7.1
A buffer handling flaw in Zephyr's Bluetooth ISO receive path allows an attacker with access to an established Bluetooth connection to read and write memory beyond buffer boundaries. When processing incoming ISO data packets, the code fails to validate that the packet contains enough bytes before extracting header information.

- CVE-2026-49295HIGH 7.1
libde265, an open-source H.265 video codec library, contains a flaw where a specially crafted video file can cause the decoder to write data beyond the boundaries of an internal array. This happens during the processing of reference picture sets—a critical step in decoding H.265 video. The vulnerability can lead to application crashes or memory corruption, affecting any system that uses libde265 to decode H.265 video streams. The issue was patched in version 1.0.20.
- CVE-2026-49839HIGH 7.1
jq is a widely-used command-line tool for processing JSON data. This vulnerability exists in how jq handles very large files when using the `--rawfile` option. When jq reads an oversized file, it is supposed to stop and report an error once the file exceeds the string size limit. However, in versions before 1.8.2, the error handling is incomplete: the tool continues trying to read more data from the file even after detecting it is too large. This causes jq to write data to memory locations it shouldn't access, potentially leading to a crash or allowing an attacker to execute code. An attacker would need to trick a user into running jq on a specially crafted large file.
- CVE-2026-53041HIGH 7.1
A flaw in how the Linux kernel's OCFS2 filesystem reports extended file attributes (xattrs) can cause a kernel crash when listing these attributes on files that store them in multiple locations. When a file's inline xattrs exactly fill a user's buffer and there are additional xattrs stored in blocks, the kernel incorrectly reports a size that exceeds the buffer and then attempts to write beyond it, triggering a kernel panic. This affects systems using OCFS2 as their filesystem, particularly in Oracle environments and high-availability clusters.
- CVE-2026-53187HIGH 7.1
A vulnerability exists in the Linux kernel's RDMA (Remote Direct Memory Access) subsystem where user-supplied CPU IDs are not properly validated before being used in system operations. An attacker with local access can supply an invalid CPU ID that causes the kernel to read memory outside the valid CPU bitmap range, potentially exposing sensitive information or crashing the system. This is particularly dangerous on systems configured to panic when kernel warnings are triggered.
- CVE-2026-53203HIGH 7.1
A buffer overflow vulnerability exists in the Linux kernel's Intel VPU (Vision Processing Unit) acceleration driver. When the driver queries metric stream information from firmware, it does not properly validate whether the returned data size exceeds the allocated buffer. An attacker with local access could trigger this condition, potentially leading to information disclosure or system instability. The vulnerability affects systems running vulnerable Linux kernel versions with the Intel VPU driver enabled.
- CVE-2026-53205HIGH 7.1
The Linux kernel contains a vulnerability in the Intel VPU (Video Processing Unit) acceleration driver where firmware-supplied log buffer indices are not properly validated. When the firmware provides read or write indices that fall outside the valid range of the log buffer, the kernel does not catch this before using them to access memory. This can lead to the kernel reading from or writing to unintended memory locations, potentially exposing sensitive data or causing system instability. The fix adds validation to ensure indices stay within bounds and clamps out-of-range values to safe defaults.
- CVE-2026-56209HIGH 7.1
A critical flaw exists in libaom, the open-source reference implementation of the AV1 video codec. An attacker can craft malicious video frames that exploit a missing validation check in the Scalable Video Coding layer, allowing them to write data to arbitrary memory locations on a system running a vulnerable encoder. This could crash the encoder (denial of service) or potentially allow the attacker to execute arbitrary code. The vulnerability is particularly dangerous because it requires no prior information disclosure to exploit—an attacker who can feed frames to a network-accessible encoder, such as in a transcoding service or live stream ingestion pipeline, can trigger the flaw reliably.
- CVE-2026-56211HIGH 7.1
A vulnerability in libaom, the open-source AV1 video codec library, allows an attacker to execute arbitrary code on systems that process untrusted video files with scalable video coding (SVC) features enabled. An attacker crafts malicious video frames that bypass safety checks in the encoder, allowing them to corrupt memory structures that control how the encoder operates. In services that spawn separate processes to handle video encoding, this memory corruption can be leveraged to discover the process layout in memory and ultimately redirect execution to attacker-controlled code. Exploitation requires that the target application uses libaom with SVC encoding active and processes video frames from an untrusted source.
- CVE-2026-59691HIGH 7.1
A flaw in GStreamer's RFB/VNC plugin (rfbsrc) allows a remote attacker to crash applications or corrupt memory when a user connects to a malicious video streaming server. The vulnerability stems from a mismatch between expected and actual data sizes: the plugin allocates a buffer for 16-bit pixel values but then writes 32-bit values into it during certain screen update operations. An attacker controlling a fake RFB server can exploit this by advertising a 16-bit display mode and sending specially crafted graphical updates, triggering a heap overflow that impacts any GStreamer-based media application using the rfbsrc plugin.
- CVE-2026-59948HIGH 7.0
Composer, the widely-used PHP dependency manager, contains a vulnerability that allows attackers to place malicious files anywhere on a developer's system during package installation or updates. An attacker who controls a third-party repository can craft a package with an invalid name that bypasses validation checks, letting them write files outside the intended vendor directory. This is a local-impact vulnerability requiring user interaction (installing or updating packages), but the consequences are severe: an attacker can modify system files, inject code into projects, or disrupt operations. The issue affects all versions of Composer before 2.2.29 and 2.10.2.
- CVE-2026-53196MEDIUM 6.8
A vulnerability in the Linux kernel's USB serial driver for IO Technic devices allows a malicious USB device to overflow kernel memory when connected to a host system. The driver fails to properly validate the size of data it reads from a device's onboard memory, trusting an untrusted value from the device itself. When a crafted device is plugged in, it can write far more data into a small kernel buffer than it was designed to hold, potentially leading to code execution or system crash.
- CVE-2025-10238MEDIUM 6.7
A vulnerability in ThinkPad BIOS could allow someone with administrative or system-level access to a machine to write data outside intended memory boundaries, potentially enabling them to execute malicious code at the System Management Mode (SMM) level. SMM is a privileged processor mode that runs independently of the operating system, giving an attacker the ability to compromise the system at its deepest firmware level.
- CVE-2025-59614MEDIUM 6.7
A memory corruption flaw exists in multiple Qualcomm components when processing random number generator commands with an undersized output buffer. An attacker with high-level privileges on the local system can trigger this condition to corrupt memory, potentially achieving confidentiality, integrity, and availability compromise. The vulnerability requires administrator or equivalent access and cannot be exploited remotely.
- CVE-2026-20453MEDIUM 6.7
CVE-2026-20453 is a local privilege escalation vulnerability in MediaTek's geniezone component affecting multiple SoC (System-on-Chip) firmware and chipsets. The flaw stems from missing bounds validation during a write operation, allowing an attacker who already has system-level privileges to escalate further or corrupt memory. Because the attack requires prior system access and involves no user interaction, this is a post-compromise risk rather than an initial attack vector. The vulnerability carries a CVSS 3.1 score of 6.7 (Medium severity).
- CVE-2026-10999MEDIUM 6.5
An integer overflow vulnerability exists in ANGLE (a graphics abstraction layer) within Google Chrome on Windows. Before version 149.0.7827.53, this flaw could allow an attacker who already controls the Chrome renderer process to read sensitive data from memory by tricking a user into viewing a specially crafted webpage. The vulnerability requires user interaction (clicking a link or visiting a malicious site) but does not allow the attacker to modify data or crash the browser.
- CVE-2026-11090MEDIUM 6.5
