CVE-2026-53063

A flaw was found in the Linux kernel's device-mapper (dm) cache component. Incomplete logic within the invalidate_remove() function, which handles write operations after cache invalidation, can lead to a system hang. This occurs because the function sets up remapping for write operations but fails to submit them, causing write operations to indefinitely wait for completion. This vulnerability could allow a local attacker to cause a Denial of Service (DoS) by triggering a write hang.
