{"id":"CVE-2026-97552","published":"2026-09-25T11:17:05.647","lastModified":"2026-09-25T11:17:05.647","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nxfs: initialise error in xfs_defer_finish_one()\n\nxfs_defer_finish_one() declares error without an initialiser and only\nassigns it inside the loop over dfp->dfp_work.  When that list is empty\nthe loop body never runs, control falls through to the \"Done with the\ndfp, free it\" path, and the function returns an indeterminate value.\n\nAn item-less pending item reaches this through xfs_defer_add_barrier(),\nwhich xfs_reap_ag_blocks() uses on any CONFIG_XFS_ONLINE_REPAIR kernel.\nxfs_defer_finish_noroll() treats any non-EAGAIN return as fatal, so a\nnon-zero stack value turns a successful barrier into a\nSHUTDOWN_CORRUPT_INCORE in the middle of a repair.  Zero is the correct\nresult: reaching the free path means the item loop drained without a\nnon-zero error.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/30748a24b9f04f9a83599ba907cc8fbff0729f3c","tags":[]},{"url":"https://git.kernel.org/stable/c/6176d21d7bd609632c5b7e87a3adb9be29ec1e72","tags":[]},{"url":"https://git.kernel.org/stable/c/6b507c239884f7d4bf8339f6e9eb8bfcb540afde","tags":[]},{"url":"https://git.kernel.org/stable/c/ba949a14446b7346e92e676ee3fe2bb79d9ce450","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
