CVE-2024-43855

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

Description A deadlock vulnerability has been resolved in the Linux kernel. The issue occurs when the kernel is being suspended while a flush bio is in progress, causing a complex deadlock scenario. The root cause is the non-atomic increment and decrement of active io during the flush process. To fix the issue, the kernel now ensures that active io is only incremented and decremented once during the entire flush process. Additionally, a WARN ON has been added to prevent future modifications from introducing issues.

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