CVE-2026-80755

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

Description An out-of-bounds heap write occurs in the SELinux component when the perm read() function fails to bound a permission value by the nprim of the owning class or common. This allows a class that declares fewer permissions than its largest permission value to cause an invalid write into an nprim-sized array allocated via kcalloc() within the security get permissions() function.

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