{"id":"CVE-2024-41080","summary":"io_uring: fix possible deadlock in io_register_iowq_max_workers()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nio_uring: fix possible deadlock in io_register_iowq_max_workers()\n\nThe io_register_iowq_max_workers() function calls io_put_sq_data(),\nwhich acquires the sqd-\u003elock without releasing the uring_lock.\nSimilar to the commit 009ad9f0c6ee (\"io_uring: drop ctx-\u003euring_lock\nbefore acquiring sqd-\u003elock\"), this can lead to a potential deadlock\nsituation.\n\nTo resolve this issue, the uring_lock is released before calling\nio_put_sq_data(), and then it is re-acquired after the function call.\n\nThis change ensures that the locks are acquired in the correct\norder, preventing the possibility of a deadlock.","modified":"2026-04-02T12:17:25.344860Z","published":"2024-07-29T15:04:17.642Z","related":["SUSE-SU-2024:3190-1","SUSE-SU-2024:3194-1","SUSE-SU-2024:3195-1","SUSE-SU-2024:3209-1","SUSE-SU-2024:3383-1","SUSE-SU-2024:3483-1","SUSE-SU-2025:20044-1","SUSE-SU-2025:20047-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/41xxx/CVE-2024-41080.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/73254a297c2dd094abec7c9efee32455ae875bdf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/950ac86cff338ab56e2eaf611f4936ee34893b63"},{"type":"WEB","url":"https://git.kernel.org/stable/c/97ed7ff58de66c544692b3c2b988f3f594348de0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b17397a0a5c56e111f61cb5b77d162664dc00de9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b571a367502c7ef94c688ef9c7f7d69a2ce3bcca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fdacd09f2ddf7a00787291f08ee48c0421e5b709"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/41xxx/CVE-2024-41080.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-41080"},{"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":"2b188cc1bb857a9d4701ae59aa7768b5124e262e"},{"fixed":"b17397a0a5c56e111f61cb5b77d162664dc00de9"},{"fixed":"97ed7ff58de66c544692b3c2b988f3f594348de0"},{"fixed":"fdacd09f2ddf7a00787291f08ee48c0421e5b709"},{"fixed":"950ac86cff338ab56e2eaf611f4936ee34893b63"},{"fixed":"b571a367502c7ef94c688ef9c7f7d69a2ce3bcca"},{"fixed":"73254a297c2dd094abec7c9efee32455ae875bdf"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-41080.json"}}],"schema_version":"1.7.5"}
