{"id":"CVE-2025-68168","summary":"jfs: fix uninitialized waitqueue in transaction manager","details":"In the Linux kernel, the following vulnerability has been resolved:\n\njfs: fix uninitialized waitqueue in transaction manager\n\nThe transaction manager initialization in txInit() was not properly\ninitializing TxBlock[0].waitor waitqueue, causing a crash when\ntxEnd(0) is called on read-only filesystems.\n\nWhen a filesystem is mounted read-only, txBegin() returns tid=0 to\nindicate no transaction. However, txEnd(0) still gets called and\ntries to access TxBlock[0].waitor via tid_to_tblock(0), but this\nwaitqueue was never initialized because the initialization loop\nstarted at index 1 instead of 0.\n\nThis causes a 'non-static key' lockdep warning and system crash:\n  INFO: trying to register non-static key in txEnd\n\nFix by ensuring all transaction blocks including TxBlock[0] have\ntheir waitqueues properly initialized during txInit().","modified":"2026-10-28T02:30:39.814944871Z","published":"2025-12-16T13:42:48.350Z","related":["SUSE-SU-2026:0278-1","SUSE-SU-2026:0281-1","SUSE-SU-2026:0293-1","SUSE-SU-2026:0315-1","SUSE-SU-2026:20477-1","SUSE-SU-2026:20498-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68168.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/038861414ab383b41dd35abbf9ff0ef715592d53"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2a9575a372182ca075070b3cd77490dcf0c951e7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/300b072df72694ea330c4c673c035253e07827b8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8cae9cf23e0bd424ac904e753639a587543ce03a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a2aa97cde9857f881920635a2e3d3b11769619c5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cbf2f527ae4ca7c7dabce42e85e8deb58588a37e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d2dd7ca05a11685c314e62802a55e8d67a90e974"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d6af7fce2e162ac68e85d3a11eb6ac8c35b24b64"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68168.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68168"},{"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":"2a8807f9f511c64de0c7cc9900a1683e3d72a3e5"},{"fixed":"d6af7fce2e162ac68e85d3a11eb6ac8c35b24b64"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5c094ca994824e038b6a97835ded4e5d1d808504"},{"fixed":"8cae9cf23e0bd424ac904e753639a587543ce03a"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"2febd5f81e4bfba61d9f374dcca628aff374cc56"},{"fixed":"a2aa97cde9857f881920635a2e3d3b11769619c5"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"aa7cdf487ab3fa47284daaccc3d7d5de01c6a84c"},{"fixed":"d2dd7ca05a11685c314e62802a55e8d67a90e974"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"95e2b352c03b0a86c5717ba1d24ea20969abcacc"},{"fixed":"2a9575a372182ca075070b3cd77490dcf0c951e7"},{"fixed":"cbf2f527ae4ca7c7dabce42e85e8deb58588a37e"},{"fixed":"038861414ab383b41dd35abbf9ff0ef715592d53"},{"fixed":"300b072df72694ea330c4c673c035253e07827b8"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5.4.255"},{"fixed":"5.4.302"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5.10.192"},{"fixed":"5.10.247"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5.15.123"},{"fixed":"5.15.197"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.1.42"},{"fixed":"6.1.159"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.14.324"},{"fixed":"4.15"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.19.293"},{"fixed":"4.20"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.4.7"},{"fixed":"6.5"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"a88efca805bea93cea9187dfd00835aa7093bf1b"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"97c1f26e4d4af55e8584e4646dd5c5fa7baf62c7"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"b0ed8ed0428ee96092da6fefa5cfacbe4abed701"}]}],"versions":["v5.4.301","v5.4.300","v5.4.299","v5.4.298","v5.4.297","v5.4.296","v5.4.295","v5.4.294","v5.4.293","v5.4.292","v5.4.291","v5.4.290","v5.4.289","v5.4.288","v5.4.287","v5.4.286","v5.4.285","v5.4.284","v5.4.283","v5.4.282","v5.4.281","v5.4.280","v5.4.279","v5.4.278","v5.4.277","v5.4.276","v5.4.275","v5.4.274","v5.4.273","v5.4.272","v5.4.271","v5.4.270","v5.4.269","v5.4.268","v5.4.267","v5.4.266","v5.4.265","v5.4.264","v5.4.263","v5.4.262","v5.4.261","v5.4.260","v5.4.259","v5.4.258","v5.4.257","v5.4.256","v5.4.255","v5.10.246","v5.10.245","v5.10.244","v5.10.243","v5.10.242","v5.10.241","v5.10.240","v5.10.239","v5.10.238","v5.10.237","v5.10.236","v5.10.235","v5.10.234","v5.10.233","v5.10.232","v5.10.231","v5.10.230","v5.10.229","v5.10.228","v5.10.227","v5.10
