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 6.12.113, 6.18.56, 7.2.10 or higher.
Overview
Affected versions of this package are vulnerable to Out-of-Bounds through the fixed_rate_idx debugfs attribute, which allows arbitrary values to be written and subsequently used as array indices in internal data structures. An attacker can corrupt adjacent kernel memory by writing out-of-bounds values to this attribute. This is only exploitable if the attacker has root access and can write to a mounted debugfs 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
