CVE-2026-53063

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the dm cache passthrough mode where the invalidate remove() function contains incomplete logic for handling write hit bios following cache invalidation. The system sets up remapping for the overwrite bio but drops it without submission, which leads to write operations hanging. This is addressed by implementing an invalidate committed() continuation to submit remapped writes to the cache origin after metadata commit completes, utilizing the overwrite endio hook for proper completion sequencing. Additionally, error handling in invalidate complete() is improved to preserve the original error status instead of unconditionally using bio io error().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
