{"id":"CVE-2026-53287","summary":"audit: fix incorrect inheritable capability in CAPSET records","details":"In the Linux kernel, the following vulnerability has been resolved:\n\naudit: fix incorrect inheritable capability in CAPSET records\n\n__audit_log_capset() records the effective capability set into the\ninheritable field due to a copy-paste error. Every CAPSET audit\nrecord therefore reports cap_pi (process inheritable) with the value\nof cap_effective instead of cap_inheritable.\n\nThis silently corrupts audit data used for compliance and forensic\nanalysis: an attacker who modifies inheritable capabilities to\nprepare for a privilege-escalating exec would have the change masked\nin the audit trail.\n\nThe bug has been present since the original introduction of CAPSET\naudit records in 2008.","modified":"2026-07-09T18:30:05.344856577Z","published":"2026-06-26T19:40:47.946Z","related":["SUSE-SU-2026:22521-1","SUSE-SU-2026:22522-1","SUSE-SU-2026:2799-1","SUSE-SU-2026:2800-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53287.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0a065c51a225854768b772a0b733a44d77162582"},{"type":"WEB","url":"https://git.kernel.org/stable/c/151ee470edc3d7ed29fe72df678f8357d2ad8ced"},{"type":"WEB","url":"https://git.kernel.org/stable/c/75bd76c9eb2de9afeca03dc5152ebca5fb8fc816"},{"type":"WEB","url":"https://git.kernel.org/stable/c/95de7bb4bf535a9288549d401ebde83cdcbf2792"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d782e4d200cd9036ef353eeb29525bfbfd13a14e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e35f3550c5b4fab33103c18654c293cee9850b0a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e4a640475e43f406fdfd56d370b1f34b0cbbc18d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/febb4bf373ac565d3fb8d1f429827bdd983be496"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53287.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53287"},{"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":"e68b75a027bb94066576139ee33676264f867b87"},{"fixed":"75bd76c9eb2de9afeca03dc5152ebca5fb8fc816"},{"fixed":"febb4bf373ac565d3fb8d1f429827bdd983be496"},{"fixed":"95de7bb4bf535a9288549d401ebde83cdcbf2792"},{"fixed":"151ee470edc3d7ed29fe72df678f8357d2ad8ced"},{"fixed":"0a065c51a225854768b772a0b733a44d77162582"},{"fixed":"e35f3550c5b4fab33103c18654c293cee9850b0a"},{"fixed":"d782e4d200cd9036ef353eeb29525bfbfd13a14e"},{"fixed":"e4a640475e43f406fdfd56d370b1f34b0cbbc18d"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53287.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.29"},{"fixed":"5.10.258"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.209"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.175"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.141"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.91"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.33"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53287.json"}}],"schema_version":"1.7.5"}
