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

Description The Linux kernel contains an issue where a silent deadlock can occur between the PG locked bit and the ni lock lock within the ntfs3 filesystem. This deadlock arises because filemap update page() calls filemap read folio() after calling folio trylock(), which sets the PG locked bit. Subsequently, ntfs truncate() calls truncate setsize(), which waits for the PG locked bit to be cleared while holding the ni lock lock, leading to a hung task at do user addr fault().

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