  • CVE-2026-47328MEDIUM 6.1

    Ubuntu Linux kernels 6.8, 6.17, and 7.0 contain a memory management bug in AppArmor SAUCE patches that allows unprivileged local users to corrupt kernel memory and exhaust system resources. The vulnerability stems from incorrect pointer deallocation—the code attempts to free memory that was never properly allocated, while simultaneously leaking other allocated memory. This combination can destabilize the kernel's memory management structures.
