Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A circular locking dependency exists in the ntfs3 component, specifically within the
run unpack ex() function. This issue occurs due to an AB-BA deadlock scenario where ntfs extend mft() acquires ni->file.run lock followed by wnd->rw lock, while run unpack ex() acquires wnd->rw lock and subsequently attempts to acquire ni->file.run lock inside ntfs refresh zone(). An AB-BA deadlock is a situation where two different threads are waiting for each other to release locks, causing the system to hang.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
