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, specifically in the dm-raid456 and md/raid456 modules. The issue occurs when IO operations are concurrent with reshape operations. In certain cases, such as when the array is read-only, MD RECOVERY WAIT is set, or MD RECOVERY FROZEN is set, the reshape operation will never make progress, causing IO operations to hang. The problem does not exist in md/raid because the register new sync thread does not rely on IO being done. The patch ensures that raid message() cannot change sync thread() through raid message() after presuspend() and detects the above cases before waiting for IO to be done in dm suspend(), allowing dm-raid to requeue those IO operations.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
