Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Overview
Affected versions of this package are vulnerable to Improper Privilege Management in the automount process for NFS filesystems. An attacker can cause incorrect capability inheritance by providing a malicious NFS server or performing a man-in-the-middle attack, leading to exposure of file metadata, incorrect file ownership, and denial of access to certain subtrees.
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
