CVE-2026-23411

A flaw was found in the Linux kernel's AppArmor security module. A race condition occurs when AppArmor incorrectly manages the lifecycle of i_private data, leading to situations where data is freed while still being accessed by file system callback functions. This timing vulnerability can result in memory corruption. A local attacker could potentially exploit this flaw to cause a denial of service or, with further exploitation, achieve more severe impacts.
