CVE-2026-72462
HighCVSS 8.8Exploitation Probability (EPSS)
Low risk4th percentile - higher than 4% of all known CVEs
Summary
In the Linux kernel's AppArmor module, a race condition exists in Unix socket mediation when peer_path is used. Accessing the path outside the state lock allows a race with unix_release_sock(), potentially leading to use-after-free.
Risk Assessment
An attacker could exploit the race to corrupt data or gain unauthorized access to resources.
Recommendation
Apply a Linux kernel update containing the fix that takes the state lock and gets a reference to the path under lock.
Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: apparmor: fix race in unix socket mediation when peer_path is used The holding a reference to the peer_sk is not enough to ensure access to the peer sk path. Accessing the path outside of the state lock allows for a race with unix_release_sock(). Fix this by taking the state lock and getting a reference to the path under lock. Ideally for connected sockets we would cache this information so we don't have to take the lock here. But for now just fix the race.
