In the Linux kernel, the following vulnerability has been resolved: ext4: don't set EXT4GETBLOCKSCONVERT when splitting before submitting I/O When allocating blocks during within-EOF DIO and writeback with dioreadnolock enabled, EXT4GETBLOCKSPREIO was set to split an existing large unwritten...

CVE-2026-46080

The CVE-2026-46080 entry documents a Linux kernel OCFS2 issue where JBD2 credit exhaustion during direct I/O writes could trigger warnings. The fix addresses this by: (1) splitting and batching extent operations in ocfs2_dio_end_io_write to prevent exceeding journal credits, (2) relocating ocfs2_...

CVE-2026-46017

The CVE relates to the Linux kernel memory management migration path. A race in the deferred split queue during folio migration could mark a destination folio as partially mapped and trip a WARN in deferred_split_folio() when dst becomes visible before it is requeued. The fix realigns the sequenc...

CVE-2026-45985

CVE-2026-45985 — Summary (CONCRETE DETAILS) Impact: Linux kernel ext4 block mapping during within-EOF DIO/writeback with dioread_nolock can convert an unwritten on-disk extent to written during a split, potentially exposing stale data if a write fails. Affected component: ext4 block mapping and e...

CVE-2026-45940 net: stmmac: fix oops when split header is enabled

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: fix oops when split header is enabled For GMAC4, when split header is enabled, in some rare cases, the hardware does not fill buf2 of the first descriptor with payload. Thus we cannot assume buf2 is always fully fill...

Thus we cannot assume buf2 is always fully fill...

CVE-2026-45940

In the Linux kernel, CVE-2026-45940 affects the stmmac driver (GMAC4) and is resolved by changing the descriptor handling: the PL bit-field in RDES3 is now applied to all descriptors, whether last or not. Previously, some descriptors could have buf2 not fully filled, causing incorrect length calc...

CVE-2026-45912

The CVE-2026-45912 issue affects the Linux kernel ext4 path: during split of an unwritten extent, ext4_split_extent_at() truncates and inserts a new extent while the extent status tree may temporarily reflect a hole if ext4_find_extent() or ext4_cache_extents() are invoked. This can leave a stale...

In the Linux kernel, the following vulnerability has been resolved: powerpc/eeh: fix recursive pcilockrescanremove locking in EEH event handling The recent commit 1010b4c012b0 "powerpc/eeh: Make EEH driver device hotplug safe" restructured the EEH driver to improve synchronization with the PCI...

CVE-2026-45899

Summary: CVE-2026-45899 is a Linux kernel ext4 issue corrected by dropping all remaining potentially stale extents when a split extent operation fails. What happens: If a split extent fails, some extents may remain in processing and an error is returned, leaving stale entries in the extent status...
