A flaw was found in the Xorg-x11-server. The specific flaw exists within
the handling of ProcXkbSetDeviceInfo requests. The issue results from the
lack of proper validation of user-supplied data, which can result in a
memory access past the end of an allocated buffer. This flaw allows an
attacker to escalate privileges and execute arbitrary code in the context
of root.

Notes
