CVE-2026-80757

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An out-of-bounds heap write exists in the SELinux component. The class read() function accepts a permission count nprim from the policy image without verifying if it covers the inherited common permissions. When security get permissions() maps these inherited permissions into an array sized by nprim, a class declaring a smaller nprim than its inherited common permissions allows data to be written past the array boundaries.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
