{"id":"CVE-2026-72459","summary":"apparmor: aa_label_alloc use aa_label_free on alloc failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\napparmor: aa_label_alloc use aa_label_free on alloc failure\n\naa_label_alloc() allocates a secid before allocating or taking the label\nproxy. If the later proxy step fails, the error path only freed the label\nmemory, leaking any resources initialized by aa_label_init().\n\nUse aa_label_free() on the failure path so partially initialized labels\nrelease their secid and other label resources before the backing memory is\nfreed.","modified":"2026-08-18T03:56:56.460718859Z","published":"2026-08-15T05:57:04.794Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72459.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/654fe7505dc6889724d4094fa64f89991afabfc3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6d91479174240f39e9edea250d95fa08c678a207"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7cb69e109610bba500e1ecb870f7988a4717208a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ae02e603c0b39b29f3ce6fe3efe01b286af1a2a4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b14fbacad77d64594228983ec20d61a224f3f491"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b5a9da5d36162d34db0f36abb15420e295176793"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bf310b044e85d4de670c94295c5d8e4c5bc5e7bc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cc2192899d502e3321e60cf1e91421e7309d089c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72459.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72459"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"f1bd904175e8190ce14aedee37e207ab51fe3b30"},{"fixed":"b14fbacad77d64594228983ec20d61a224f3f491"},{"fixed":"b5a9da5d36162d34db0f36abb15420e295176793"},{"fixed":"7cb69e109610bba500e1ecb870f7988a4717208a"},{"fixed":"cc2192899d502e3321e60cf1e91421e7309d089c"},{"fixed":"bf310b044e85d4de670c94295c5d8e4c5bc5e7bc"},{"fixed":"ae02e603c0b39b29f3ce6fe3efe01b286af1a2a4"},{"fixed":"6d91479174240f39e9edea250d95fa08c678a207"},{"fixed":"654fe7505dc6889724d4094fa64f89991afabfc3"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72459.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.13.0"},{"fixed":"5.10.261"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.212"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72459.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
