Local privilege escalation via out-of-bounds write
Published Feb 17, 2021 · Updated Aug 4, 2024
Out-of-bounds write in Intel Graphics Drivers before 26.20.100.8336 allows local users to escalate privileges via local access. The affected graphics-driver code writes beyond a valid buffer boundary while handling local input, corrupting memory in a privileged driver context. Exploitation requires a privileged local user; successful corruption can raise that user's privileges, while the advisory does not establish remote reachability or a guaranteed service interruption.
