{"id":"CVE-2026-72462","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-72462","summary":"apparmor: fix race in unix socket mediation when peer_path is used","details":"In the Linux kernel, the following vulnerability has been resolved:\n\napparmor: fix race in unix socket mediation when peer_path is used\n\nThe holding a reference to the peer_sk is not enough to ensure access\nto the peer sk path. Accessing the path outside of the state lock\nallows for a race with unix_release_sock(). Fix this by taking the\nstate lock and getting a reference to the path under lock.\n\nIdeally for connected sockets we would cache this information so we\ndon't have to take the lock here. But for now just fix the race.","published":"2026-08-15T05:57:06.705Z","modified":"2026-08-16T03:48:42.652886767Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.18.40"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/b1aea2c1960771a276d7e68c7424168eccd0c3da"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d680472db98823d90fc91362910901e468269318"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d8ea44f6090c087fe255d9512fb808574b4d88e8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72462.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72462"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-16T03:48:42.652886767Z"}}
