CVE-2026-72200

In the Linux kernel, the following vulnerability has been resolved: ntfs: detect mapping-pairs LCN accumulator overflow The NTFS mapping-pairs parser accumulates relative LCN deltas in a signed integer. A corrupted attribute can drive that addition past the representable range. One corrupt runlis...

CVE-2026-72201

In the Linux kernel, the following vulnerability has been resolved: ntfs: validate index entries on reading Validate index entries immediately after reading an index root or index block from disk. This eliminates repeated checks in lookup and readdir, and reduce the risk of missing checks in thos...

CVE-2026-72198

In the Linux kernel, the following vulnerability has been resolved: ntfs: reject non-resident records for resident-only attributes The shared lookup-time attribute validator rejects non-resident $FILENAME and $VOLUMENAME records because their formats require resident values and callers handle...

CVE-2026-72187

In the Linux kernel, the following vulnerability has been resolved: ntfs: avoid self-deadlock during inode eviction An attribute-list update performed while allocating clusters can drop the last reference to the temporary attribute inode. Evicting that inode drops its reference to the base inode...

CVE-2026-72188

In the Linux kernel, the following vulnerability has been resolved: ntfs: sanitize MFT references returned from ntfslookupinodebyname ntfslookupinodebyname returns MFT references read from directory index entries on disk. These values are untrusted, but the function can currently return an...

CVE-2026-72190

In the Linux kernel, the following vulnerability has been resolved: ntfs: fix mreclock ABBA deadlock in rename ntfsfilefsync, ntfsdirfsync and ntfswriteinode lock an inode's mreclock before taking the mreclock of its parent directory. ntfsrename takes oldni-mreclock and olddirni-mreclock before...

CVE-2026-72189

In the Linux kernel, the following vulnerability has been resolved: ntfs: fail attrlist updates when the superblock is inactive genericshutdownsuper clears SBACTIVE before evicting cached inodes. If eviction selects the fake inode for a base inode's unnamed $ATTRIBUTELIST attribute,...

CVE-2026-72185

In the Linux kernel, the following vulnerability has been resolved: ntfs: fix WARNON for resident attribute in ntfsmaprunlistnolock When ntfsmaprunlistnolock needs to look up the attribute extent containing a target VCN ctxneedsreset == true, it calls ntfsattrlookup and then expects the result to...

CVE-2026-72184

In the Linux kernel, the following vulnerability has been resolved: ntfs: fix hole runlist memory leak in insert range error path ntfsnonresidentattrinsertrange allocates holerl before mapping the whole runlist. If ntfsattrmapwholerunlist fails, the error path drops ni-runlist.lock and returns...

CVE-2026-72186

In the Linux kernel, the following vulnerability has been resolved: ntfs: make system files immutable to prevent corruption When a system file such as $Bitmap is exposed via showsysfiles and written from userspace, the volume is corrupted and, because the cluster allocator scans $Bitmap through t...

UBUNTU-CVE-2026-72207

In the Linux kernel, the following vulnerability has been resolved: ntfs: not change 0-byte $DATA attribute to non-resident When ntfsresidentattrresize cannot grow a resident attribute in place, it retries after converting other resident attributes to non-resident to free space in the MFT recrord...

UBUNTU-CVE-2026-72204

In the Linux kernel, the following vulnerability has been resolved: ntfs: centalize $INDEXROOT header validation Add a dedicated helper to perform stricter validation of $INDEXROOT and use it for both directory inodes and named index inodes. This keeps the root size and header geometry checks...

UBUNTU-CVE-2026-72202

In the Linux kernel, the following vulnerability has been resolved: ntfs: avoid heap allocation for free-cluster readahead state getnrfreeclusters allocates a temporary filerastate before it publishes the precomputed free cluster count, sets NVolFreeClusterKnown, and wakes vol-freewaitq. If that...

UBUNTU-CVE-2026-72211

In the Linux kernel, the following vulnerability has been resolved: ntfs: grow index root value before reparent header update ntfsirreparent moves the resident index root entries into an index block and leaves a small root stub containing the child VCN. That root stub can be larger than the...
