CVE-2026-72354

Summary: CVE-2026-72354 affects the Linux kernel NTFS MFT writeback code, where a runlist_element borrowed under ni->runlist.lock can be freed by ntfs_rl_realloc during a concurrent $MFT extension. If the old runlist backing storage is freed after the lookup but before folio sizing, a use-afte...

EUVD-2026-59253

In the Linux kernel, the following vulnerability has been resolved: ntfs: avoid stale runlist element dereference in MFT writeback ntfswritemftblock maps each $MFT record through the $MFT data runlist. For sub-folio clusters it looks up a struct runlistelement under ni-runlist.lock, drops the loc...

CVE-2026-72203

CVE-2026-72203 concerns the Linux kernel NTFS driver and describes a deadlock (ABBA) between extent_lock and extent mrec_lock triggered by writes to normal extents and the $MFT folio. The fix removes all extent_lock and extent mrec_lock acquisitions from the MFT folio writeback path, eliminating ...

CVE-2026-72188

The CVE-2026-72188 issue affects the Linux kernel NTFS handling: ntfs_lookup_inode_by_name() can return error-marked MFT references without validation, causing callers to misinterpret a MREF_ERR() with arbitrary low bits as a valid result. The vulnerability stems from untrusted on-disk MFT refere...
