Improper Restriction of Operations within the Bounds of a Memory Buffer Affecting torvalds/linux package, versions [3.8,6.12.35)[6.13,6.15.4)
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 6.12.35, 6.15.4 or higher.
Overview
Affected versions of this package are vulnerable to Improper Restriction of Operations within the Bounds of a Memory Buffer in the get_new_segment process. An attacker can cause data corruption, information disclosure, and denial of service by manipulating on-disk metadata on a locally mounted F2FS volume, leading to inconsistent segment allocation and overlapping block mappings. This can result in physical overwriting of live data, corruption of filesystem structures, and persistent damage across reboots. This is only exploitable if an attacker has local write access to a mounted F2FS filesystem.
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
