Remote Code Execution (RCE) Affecting torvalds/linux package, versions [3.8,6.17.2)
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.

Upgrade torvalds/linux to version 6.17.2 or higher.
Overview
Affected versions of this package are vulnerable to Remote Code Execution (RCE) in the f2fs_truncate_hole process. An attacker can execute arbitrary code, cause kernel memory corruption, or crash the system by mounting a crafted f2fs filesystem image and performing file operations such as fallocate or read. This is only exploitable if a malicious filesystem image is mounted and the attacker can trigger file operations on it.
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
