Overview

Affected versions of this package are vulnerable to Remote Code Execution (RCE) in the ff_layout_alloc_lseg process. An attacker can cause a kernel panic and deny service by sending a crafted NFSv4 pNFS flexfiles layout with a zero filehandle version count to a vulnerable client over the network.

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
