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.

CVE-2025-68378 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 5.11, 5.16, 5.17, 5.18, 6.1.191, 6.6.160, 6.12.63, 6.17.13, 6.18.2 or higher.
Overview
Affected versions of this package are vulnerable to Information Exposure through the __bpf_get_stackid function. An attacker can cause an out-of-bounds write in the stack map bucket's data array by providing a perf trace containing more stack entries than the bucket can accommodate.
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
