{"id":"CVE-2022-3910","details":"Use After Free vulnerability in Linux Kernel allows Privilege Escalation. An improper Update of Reference Count in io_uring leads to Use-After-Free and Local Privilege Escalation.\nWhen io_msg_ring was invoked with a fixed file, it called io_fput_file() which improperly decreased its reference count (leading to Use-After-Free and Local Privilege Escalation). Fixed files are permanently registered to the ring, and should not be put separately.\n\nWe recommend upgrading past commit  https://github.com/torvalds/linux/commit/fc7222c3a9f56271fba02aabbfbae999042f1679 https://github.com/torvalds/linux/commit/fc7222c3a9f56271fba02aabbfbae999042f1679 \n","modified":"2026-03-14T11:51:53.799275Z","published":"2022-11-22T13:15:13.167Z","references":[{"type":"FIX","url":"https://github.com/torvalds/linux/commit/fc7222c3a9f56271fba02aabbfbae999042f1679"},{"type":"FIX","url":"https://kernel.dance/#fc7222c3a9f56271fba02aabbfbae999042f1679"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-3910.json","unresolved_ranges":[{"events":[{"introduced":"5.18"},{"fixed":"5.19.11"}]},{"events":[{"introduced":"0"},{"last_affected":"6.0-rc1"}]},{"events":[{"introduced":"0"},{"last_affected":"6.0-rc2"}]},{"events":[{"introduced":"0"},{"last_affected":"6.0-rc3"}]},{"events":[{"introduced":"0"},{"last_affected":"6.0-rc4"}]},{"events":[{"introduced":"0"},{"last_affected":"6.0-rc5"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
