CVE-2026-53063

A flaw was found in the Linux kernel's device-mapper dm cache component. Incomplete logic within the invalidateremove 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...
