EUVD-2026-38932

In the Linux kernel, the following vulnerability has been resolved: dm cache: fix null-deref with concurrent writes in passthrough mode In passthrough mode, when dm-cache starts to invalidate a cache entry and bio prison cell lock fails due to concurrent write to the same cached block, mg-cell...

CVE-2026-53064

In Linux kernel dm-cache passthrough mode, a race between invalidate_complete() and concurrent writes can leave mg->cell NULL, causing a NULL pointer dereference during unlock/free. The reported fix is to validate mg->cell before unlocking it. Affected context described includes local, low-...

CVE-2026-53063 dm cache: fix write hang in passthrough mode

In the Linux kernel, the following vulnerability has been resolved: dm cache: fix write hang in passthrough mode The invalidateremove function has incomplete logic for handling write hit bios after cache invalidation. It sets up the remapping for the overwritebio but then drops it immediately...

CVE-2026-53063

CVE-2026-53063 concerns the Linux kernel dm-cache passthrough path, where invalidate_remove() mishandled write hit bios after cache invalidation, causing write hangs.
