CVE-2026-80535 xfs: don't double-lock when deleting a self-referential directory

In the Linux kernel, the following vulnerability has been resolved: xfs: don't double-lock when deleting a self-referential directory LOLLM notices that the dirtree scrubber can detect a directory that refers to itself. In this case, it's not correct for the directory tree repair code to try to...

CVE-2026-80534

CVE-2026-80534 is a lock-leak bug in the XFS filesystem of the Linux kernel. The function xfs_dq_get_next_id() acquires the quota inode ILock before calling xfs_iread_extents() ; if that call fails, the function returns early without releasing the lock, leaving the quota inode permanently locked....

CVE-2026-80535

CVE-2026-80535 affects the Linux kernel XFS file system. The dirtree scrubber can detect a directory that refers to itself; in that case, the directory tree repair code incorrectly attempts to iolock/ilock both sc->ip and dp, which are the same inode, resulting in a double-lock . The fix detec...

CVE-2026-80534 xfs: fix ilock leak on error in xfs_dq_get_next_id

In the Linux kernel, the following vulnerability has been resolved: xfs: fix ilock leak on error in xfsdqgetnextid xfsdqgetnextid takes the quota inode ILOCK before calling xfsireadextents. If xfsireadextents fails, the function returns immediately without releasing the lock, leaking the quota...

CVE-2026-80533 xfs: don't walk off the end of a null sc->sa.agi_bp in AGI repair

In the Linux kernel, the following vulnerability has been resolved: xfs: don't walk off the end of a null sc-sa.agibp in AGI repair LOLLM noticed a longstanding bug where xrepiunlinkwalkondiskbucket tries to walk ragi-sc-sa.agibp to rebuild the unlinked inode lists. Unfortunately, it's possible f...

CVE-2026-80533

CVE-2026-80533 is a Linux kernel bug in the XFS filesystem's AGI repair path. The function xrep_iunlink_walk_ondisk_bucket walks ragi->sc->sa.agi_bp to rebuild unlinked inode lists, but agi_bp can be null if the buffer verifier fails, causing an out-of-bounds walk. The fix substitutes ragi-...

CVE-2026-80532

CVE-2026-80532 affects the XFS filesystem in the Linux kernel , specifically the online fsck (repair) subsystem. The function xrep_iunlink_resolve_bucket , which reconstructs in-core prev/next unlinked list pointers from disk and memory before relinking lost inodes, is vulnerable to an infinite l...

CVE-2026-80532 xfs: fix another iunlink infinite loop bug in online fsck

In the Linux kernel, the following vulnerability has been resolved: xfs: fix another iunlink infinite loop bug in online fsck xrepiunlinkresolvebucket is supposed to reconstruct as much of the incore prev and next unlinked list pointers based on what it finds on disk and in memory before we move ...

CVE-2026-80531

CVE-2026-80531 is a Use-After-Free (UAF) in the XFS filesystem component of the Linux kernel, specifically in xrep_tempfile_create on the sc->tempip pointer. The UAF occurs when temporary file creation code fails after sc->tempip has been assigned, leading to a use of freed memory. Red Hat ...

CVE-2026-80531 xfs: avoid UAF on sc->tempip in xrep_tempfile_create

In the Linux kernel, the following vulnerability has been resolved: xfs: avoid UAF on sc-tempip in xreptempfilecreate LOLLM noticed a potential UAF if the tempfile creation code fails after it set sc-tempip. Fix that...

CVE-2026-80531 xfs: avoid UAF on sc->tempip in xrep_tempfile_create

In the Linux kernel, the following vulnerability has been resolved: xfs: avoid UAF on sc-tempip in xreptempfilecreate LOLLM noticed a potential UAF if the tempfile creation code fails after it set sc-tempip. Fix that...

CVE-2026-80529

CVE-2026-80529 affects the Linux kernel's XFS filesystem . In xlog_recover_dquot_commit_pass2() , a recovered dquot is validated via xfs_dqblk_verify() ; on failure the function sets error = -EFSCORRUPTED and jumps to out_release , which unconditionally returns 0. This discards the corruption err...

In the Linux kernel, the following vulnerability has been resolved: xfs: don't swallow dquot recovery verification errors xlogrecoverdquotcommitpass2 validates the recovered dquot with xfsdqblkverify and, on failure, sets error = -EFSCORRUPTED and jumps to outrelease. But outrelease unconditional...

CVE-2026-80530

This vulnerability affects the XFS filesystem in the Linux kernel. When exchanging two full-file ranges with the XFS_EXCHMAPS_INO1_WRITTEN flag, xfs_exchmaps_can_skip_mapping() can skip hole and unwritten mappings from file1, causing the post-operation cleanup to clear the reflink flag from an in...
