CVE-2026-80806

A flaw was found in the Linux kernel's ext4 filesystem. This vulnerability allows data written to newly created encrypted files to bypass encryption when the filesystem is mounted with the 'dax=always' option. This occurs due to an incorrect sequence in setting internal flags, which prevents the...

CVE-2026-93076

A flaw was found in the Linux kernel's Direct Access DAX subsystem. When a static DAX device is reconfigured, an outdated memory mapping value can persist. This prevents the system from correctly building its virtual memory map, which is essential for proper operation. This issue could lead to...

CVE-2026-93075

A flaw was found in the Linux kernel's dax/fsdev component. When a static device is unbound, the pgmap operations and owner are not properly cleared. This can lead to a use-after-free vulnerability where a subsequent memory failure event might dispatch through a stale or freed handler, potentiall...

CVE-2026-93074

A flaw was found in the Linux kernel's dax/fsdev component. An error in calculating kernel virtual addresses within the fsdevdaxdirectaccess function, specifically for multi-range devices with physical gaps, can lead to incorrect memory addressing. This issue could result in memory corruption,...

CVE-2026-93073

A flaw was found in the Linux kernel's Direct Access DAX subsystem. A race condition in the daxholdernotifyfailure function allows a concurrent operation to clear a critical pointer holderops between two reads. This can lead to a null pointer dereference, potentially enabling a local attacker to...
