That\nhook may return an error, but security_skb_classify_flow() calls it\nfrom a void path and triggers BUG_ON() if an error is returned.\n\nDisable BPF attachment to the hook to prevent a BPF LSM program from\nturning packet classification into a full panic.","modified":"2026-08-30T03:48:20.957962780Z","published":"2026-08-28T06:49:10.511Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80669.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/12091470c6b4c1c14b2de12dcbae2ada6cb6d20b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1bb3b6a5c3c5cc814eae4ff0212fdced36f8bce9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/49fa1be621dde8f526d36e5791aded8fafda1e9c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4ae780d173ef40d4f7cb76935dc2d55fbf380009"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6b44c6660aa1c9b843e450a623ac4a8484919dce"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aa265d47308775c5501073b08133623bcb5421f9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80669.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80669"},{"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":"9e4e01dfd3254c7f04f24b7c6b29596bc12332f3"},{"fixed":"aa265d47308775c5501073b08133623bcb5421f9"},{"fixed":"6b44c6660aa1c9b843e450a623ac4a8484919dce"},{"fixed":"4ae780d173ef40d4f7cb76935dc2d55fbf380009"},{"fixed":"49fa1be621dde8f526d36e5791aded8fafda1e9c"},{"fixed":"1bb3b6a5c3c5cc814eae4ff0212fdced36f8bce9"},{"fixed":"12091470c6b4c1c14b2de12dcbae2ada6cb6d20b"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80669.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.7.0"},{"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-2026-80669.json"}}],"schema_version":"1.9.0"}
