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

Description: A flaw exists in the Linux kernel related to block I/O operations. Specifically, using submit bio noacct nocheck in blk zone wplug bio work duplicates work and can lead to deadlocks when freezing a queue with pending bio write plugs. The issue arises because BIOS queued in the zone write plug have already undergone preparation in the submit bio path, including freeze protection. Bypassing this protection with submit bio noacct nocheck introduces the potential for deadlocks.

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