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-2026-68445 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 6.1.191, 6.6.148, 6.12.101, 6.18.42, 7.1.6 or higher.
Overview
Affected versions of this package are vulnerable to Information Exposure in the vc4_gem_object_mmap process. An attacker can gain arbitrary kernel memory read and write capabilities by creating a validated shader buffer object, mapping it as read-only, upgrading the mapping to writable using mprotect, and then modifying the shader code after validation. This allows bypassing the intended validation and can lead to full privilege escalation, arbitrary code execution, or system instability.
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
