Overview
Affected versions of this package are vulnerable to Use After Free due to a race condition in the f2fs_stop_gc_thread process. An attacker can trigger memory corruption or cause a system crash by exploiting concurrent operations that lead to the use of freed memory. This is only exploitable if the shutdown and remount operations occur simultaneously without proper semaphore locking.
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
