{"id":"CVE-2022-39188","details":"An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs.","modified":"2026-03-15T22:44:11.643940Z","published":"2022-09-02T05:15:07.650Z","related":["ALSA-2023:2148","ALSA-2023:2458","ALSA-2023:2736","ALSA-2023:2951","SUSE-SU-2022:3263-1","SUSE-SU-2022:3264-1","SUSE-SU-2022:3288-1","SUSE-SU-2022:3291-1","SUSE-SU-2022:3293-1","SUSE-SU-2022:3294-1","SUSE-SU-2022:3342-1","SUSE-SU-2022:3346-1","SUSE-SU-2022:3350-1","SUSE-SU-2022:3359-1","SUSE-SU-2022:3360-1","SUSE-SU-2022:3362-1","SUSE-SU-2022:3366-1","SUSE-SU-2022:3368-1","SUSE-SU-2022:3369-1","SUSE-SU-2022:3370-1","SUSE-SU-2022:3372-1","SUSE-SU-2022:3373-1","SUSE-SU-2022:3377-1","SUSE-SU-2022:3379-1","SUSE-SU-2022:3406-1","SUSE-SU-2022:3407-1","SUSE-SU-2022:3408-1","SUSE-SU-2022:3409-1","SUSE-SU-2022:3412-1","SUSE-SU-2022:3415-1","SUSE-SU-2022:3422-1","SUSE-SU-2022:3424-1","SUSE-SU-2022:3432-1","SUSE-SU-2022:3433-1","SUSE-SU-2022:3445-1","SUSE-SU-2022:3450-1","SUSE-SU-2022:3463-1","SUSE-SU-2022:3464-1","SUSE-SU-2022:3465-1","SUSE-SU-2022:3476-1","SUSE-SU-2022:3584-1","SUSE-SU-2022:3586-1","SUSE-SU-2022:3587-1","SUSE-SU-2022:3609-1","SUSE-SU-2022:3809-1","SUSE-SU-2022:4617-1","SUSE-SU-2023:0416-1"],"references":[{"type":"WEB","url":"https://lore.kernel.org/stable/CAG48ez3SEqOPcPCYGHVZv4iqEApujD5VtM3Re-tCKLDEFdEdbg%40mail.gmail.com/"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html"},{"type":"ADVISORY","url":"https://www.debian.org/security/2022/dsa-5257"},{"type":"FIX","url":"https://bugs.chromium.org/p/project-zero/issues/detail?id=2329"},{"type":"FIX","url":"https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.19"},{"type":"FIX","url":"https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b67fbebd4cf980aecbcc750e1462128bffe8ae15"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/b67fbebd4cf980aecbcc750e1462128bffe8ae15"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-39188.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"5.19"}]},{"events":[{"introduced":"0"},{"last_affected":"10.0"}]},{"events":[{"introduced":"0"},{"last_affected":"10.0"}]},{"events":[{"introduced":"0"},{"last_affected":"11.0"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
