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. Check out the EPSS documentation for more details.

Overview
Affected versions of this package are vulnerable to Buffer Overflow through the btrfs_get_name process. An attacker can cause kernel memory corruption and potentially achieve arbitrary code execution or denial of service by mounting a crafted filesystem image containing an INODE_REF item with an excessively large name length, leading to an out-of-bounds write on the kernel stack when the name is copied. This is only exploitable if the attacker is able to mount a malicious btrfs image and invoke open_by_handle_at() on the affected inode.
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
