Linux Kernel Keyctl Null Pointer Dereference Vulnerability

A malicious interaction with the keyctl usermode interface allows an attacker to crash the kernel. Processing the attached certificate by the kernel leads to a kernel nullpointer dereference. This vulnerably can be triggered by any unprivileged user locally. Local DoS: Linux Kernel Nullpointer...
