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 Out-of-Bounds in the cmp_fnames function when processing NTFS directory index entries with a malformed key_size field. An attacker can cause the kernel to read out-of-bounds memory and potentially leak sensitive information or trigger a denial of service by supplying a crafted NTFS image with a directory entry advertising a key_size larger than the actual payload. This is only exploitable if a victim, automounter, or administrator mounts the attacker's crafted NTFS image.
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
