Overview

Affected versions of this package are vulnerable to Deadlock in the run_unpack_ex process. An attacker can cause a deadlock by triggering a circular locking dependency between wnd->rw_lock and ni->file.run_lock through specific sequences of operations that manipulate NTFS file system structures.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
