CVE-2026-80913

CVE-2026-80913 affects the SELinux subsystem of the Linux kernel . The root cause is that p_bools.nprim in a loaded SELinux policy image can declare a count larger than the number of boolean values actually present, causing cond_index_bool() to leave NULL entries in bool_val_to_struct[]. Consumer...

CVE-2026-80913: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: selinux: require every boolean value to be defined pbools.nprim comes from the policy image independently of how many booleans follow it, and condindexbool fills boolvaltostruct at value - 1, so a count larger than the values...
