Overview
Affected versions of this package are vulnerable to Reachable Assertion due to inconsistent state between the NAT entry and nat bitmap in the f2fs_new_node_page process. An attacker can cause a system crash by triggering a condition where a node ID is marked as free in the nat bitmap but its corresponding NAT entry contains a non-null block address.
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
