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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/0a065c51a225854768b772a0b733a44d77162582","https://git.kernel.org/stable/c/151ee470edc3d7ed29fe72df678f8357d2ad8ced","https://git.kernel.org/stable/c/75bd76c9eb2de9afeca03dc5152ebca5fb8fc816","https://git.kernel.org/stable/c/95de7bb4bf535a9288549d401ebde83cdcbf2792","https://git.kernel.org/stable/c/d782e4d200cd9036ef353eeb29525bfbfd13a14e"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-53287","score":0.00123,"percentile":0.02,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
