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...

UBUNTU-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-2026-74351 ocfs2: rebase copied fsdlm LVB pointers in locking_state

In the Linux kernel, the following vulnerability has been resolved: ocfs2: rebase copied fsdlm LVB pointers in lockingstate The lockingstate debugfs iterator snapshots struct ocfs2lockres by value under ocfs2dlmtrackinglock and later formats that copy in ocfs2dlmseqshow. That is fine for the inli...

CVE-2026-74350

CVE-2026-74350 describes a vulnerability in the Linux kernel OCFS2 fast symlink handling. If a zero-cluster fast symlink inode has an i_size that exceeds the inline payload capacity or its payload is not exactly NUL-terminated at i_size, a memcpy during read can read past the inode block buffer, ...

CVE-2026-74350 ocfs2: validate fast symlink target during inode read

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...

CVE-2026-74351

CVE-2026-74351 affects the Linux kernel OCFS2 locking state. The root cause is a use-after-free risk where the debugfs iterator copies ocfs2_lock_res with a non-NULL sb_lvbptr that still points to an original lockres owner after teardown, leading to a freed container being accessed during dump. T...
