CVE-2026-64031

A flaw was found in the Linux kernel's erofs filesystem. A race condition exists when processing unaligned compressed extents, which can cause a managed memory page folio to be incorrectly added to the page cache multiple times. This inconsistency in memory management could allow a local attacker...

CVE-2026-64039

CVE-2026-64039 relates to the Linux kernel’s drm/msm/snapshot code, where dumping of unaligned regions caused issues because the snapshotting aligned data segments to 16 bytes. The fix removes length alignment and prints the last registers in the region more accurately; it also addresses a 16x me...
