kernel: Buffer over-read in keyring subsystem allows exposing potentially sensitive information to local attacker

A flaw has been identified in the Linux kernel's implementation of validmasterdesc in which a memory buffer would be compared to a userspace value with an incorrect size of comparison. By bruteforcing the comparison, an attacker could determine what was in memory after the description and possibl...
