Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a potential deadlock at
set capacity in the Linux kernel. This occurs due to an interrupt unsafe locking scenario where aoeblk gdalloc() holds &d->lock and attempts to acquire &bdev->bd size lock at the set capacity() call, while zram add()->set capacity() holds &bdev->bd size lock. To avoid this deadlock, the solution is to move set capacity() outside of the section protected by (&d->lock), thus breaking the lock dependency.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
