{"id":"CVE-2026-80865","summary":"bpf: Add missing access_ok call to copy_user_syms","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Add missing access_ok call to copy_user_syms\n\nAs reported by sashiko we use __get_user without prior access_ok call on the\nuser space pointer. Adding the missing call for the whole pointer array.\n\nPlus removing the err check in the error path, because it's not needed and\nalso we can return -ENOMEM directly from the first kvmalloc_array fail path.\n\n[1] https://lore.kernel.org/bpf/20260611115503.AC16D1F00893@smtp.kernel.org/","modified":"2026-09-06T03:46:59.468889891Z","published":"2026-09-04T16:48:08.582Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80865.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0b6252afcd1965f77c6a6f8a802a2e1381822b98"},{"type":"WEB","url":"https://git.kernel.org/stable/c/128391b57e0977c35243672a6f970073651f3831"},{"type":"WEB","url":"https://git.kernel.org/stable/c/28ce7bcf8a29aa395b60764df4c97be745de89d0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8b719cef5ac30ab83ce5693c5faf10e4944874af"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a67f7f9647cb243b3be32163e88e5bc76e3d51e9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d5dc200c3a3f217de072af269dd90adddf90e48d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80865.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80865"},{"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":"0236fec57a15dc2a068dfe4488e0c2ab4559b1ec"},{"fixed":"a67f7f9647cb243b3be32163e88e5bc76e3d51e9"},{"fixed":"8b719cef5ac30ab83ce5693c5faf10e4944874af"},{"fixed":"128391b57e0977c35243672a6f970073651f3831"},{"fixed":"0b6252afcd1965f77c6a6f8a802a2e1381822b98"},{"fixed":"28ce7bcf8a29aa395b60764df4c97be745de89d0"},{"fixed":"d5dc200c3a3f217de072af269dd90adddf90e48d"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80865.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.19.0"},{"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-2026-80865.json"}}],"schema_version":"1.9.0"}
