• CVE-2026-13595MEDIUM 6.8

  A memory safety bug in libblkid—a core Linux utility library responsible for identifying and reading partition tables—allows an attacker to trigger a use-after-free condition by inserting a specially crafted block device. When libblkid probes nested partitions (partitions within partitions), it caches a memory address pointing to partition information. If the system then discovers additional partitions and reallocates internal memory structures, that cached address becomes invalid. Subsequent reads from that stale pointer can leak sensitive information from kernel memory or crash the system. The risk is amplified because libblkid runs automatically with root privileges during USB insertion or when users mount disk images—no manual intervention required.
