CVE-2026-74350

In the Linux kernel, the following vulnerability has been resolved: ocfs2: validate fast symlink target during inode read ocfs2validateinodeblock already rejects several inconsistent self-contained dinodes before they are exposed to the rest of the filesystem. Fast symlinks need the same treatmen...

UBUNTU-CVE-2026-74348

In the Linux kernel, the following vulnerability has been resolved: ocfs2/dlm: require a ref for lockingstate debugfs open debuglockresopen copies inode-iprivate into struct debuglockres and debuglockresrelease later drops that pointer with dlmput. That only works if open successfully pins the...

UBUNTU-CVE-2026-74349

In the Linux kernel, the following vulnerability has been resolved: ocfs2: reject FITRIM ranges shorter than a cluster ocfs2trimmainbm trims the global bitmap in cluster units, but its too-short range validation only checks sb-sblocksize. On filesystems with a cluster size larger than the block...

CVE-2026-72163

In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix NULL htransaction deref in ocfs2assuretranscredits BUG A direct write over unwritten extents can panic the kernel in ocfs2assuretranscredits when the journal aborts during DIO completion. The crash is a general...

CVE-2026-72164

In the Linux kernel, the following vulnerability has been resolved: ocfs2: avoid moving extents to occupied clusters For non-auto OCFS2IOCMOVEEXT operations, userspace supplies a physical megoal. ocfs2moveextent initializes newphyscpos from that goal and expects ocfs2probeallocgroup to replace it...

CVE-2026-72162

In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix UBSAN array-index-out-of-bounds in ocfs2sumrightmostrec BUG On-disk corruption setting lnextfreerec to 0 in an inode's embedded extent list triggers a UBSAN panic on the next write to that file. CAUSE...

CVE-2026-72161

In the Linux kernel, the following vulnerability has been resolved: ocfs2: add journal NULL check in ocfs2checkpointinode During unmount, ocfs2journalshutdown frees the journal and sets osb-journal to NULL. Later, when VFS evicts remaining cached inodes, ocfs2evictinode - ocfs2clearinode -...

CVE-2026-72159

In the Linux kernel, the following vulnerability has been resolved: ocfs2: reject non-inline dinodes with isize and zero iclusters On a volume mounted without OCFS2FEATUREINCOMPATSPARSEALLOC, a non-inline regular file with non-zero isize and zero iclusters is structurally malformed: the extent ma...

CVE-2026-72160

In the Linux kernel, the following vulnerability has been resolved: ocfs2: reject dinodes with non-canonical imode type Patch series "ocfs2: harden inode validators against forged metadata", v2. This series adds three structural checks to OCFS2 dinode validation so malformed on-disk fields are...
