CVE-2026-53062

A flaw was found in the Linux kernel's device-mapper dm cache policy, specifically within the smq module. In passthrough mode, the invalidatemapping operation lacks proper locking, allowing for concurrent access. This can lead to data races, resulting in data corruption or use-after-free issues,...

CVE-2026-53061

A flaw was found in the Linux kernel's device-mapper dm cache component. This vulnerability arises from an incorrect assumption that table reloads only occur after suspension, which is violated by Logical Volume Manager LVM table preloading. The dirty mapping check for passthrough mode, performed...

CVE-2026-53064

Summary: CVE-2026-53064 affects the Linux kernel dm-cache when operating in passthrough mode. A race between cache invalidation and concurrent writes can leave mg->cell as NULL, causing a NULL pointer dereference in the unlock path during invalidate_complete(), triggering a KASAN null-ptr-dere...

CVE-2026-53062

The CVE-2026-53062 entry describes a Linux kernel flaw in the dm-cache policy smq in passthrough mode where invalidate_mapping is invoked concurrently by multiple workers without proper locking. This race can cause data races on the allocated blocks counter and potential use-after-free issues in ...

CVE-2026-53063

The CVE relates to the Linux kernel dm-cache subsystem in passthrough mode, where invalidate_remove() mishandled write hit bios after cache invalidation. The remapping for overwrite_bio was prepared but dropped without submission, causing write operations to hang. The fix adds an invalidate_commi...
