NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-syms-rt package and not the kernel-syms-rt package as distributed by SLES.

A flaw was found in the way RTAS handled memory accesses in userspace to kernel communication. On a locked down (usually due to Secure Boot) guest system running on top of PowerVM or KVM hypervisors (pseries platform) a root like local user could use this flaw to further increase their privileges to that of a running kernel.
