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-2026-80533

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-2026-80531

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-2026-80529

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...

CVE-2026-80530 xfs: fix exchange-range reflink flag clearing issue with INO1_WRITTEN

In the Linux kernel, the following vulnerability has been resolved: xfs: fix exchange-range reflink flag clearing issue with INO1WRITTEN When exchanging two full-file ranges, xmicanexchangereflinkflags can move the reflink inode flag from the file that currently has it to the other file, as long ...

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...

CVE-2026-74728

A flaw was found in the Linux kernel's XFS filesystem. When the system attempts to allocate memory for an XFS buffer and that allocation fails, the xfsbuffree function is called with a null buffer address. This leads to a null pointer dereference, causing the kernel to crash. This vulnerability c...
