What is CVE-2026-45201?
CVE-2026-45201 is a high-severity memory corruption vulnerability in Imagination Technologies Graphics DDK, published on 21 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
Software installed and run as a non-privileged user may conduct improper GPU system calls to pass invalid log2 page size when allocating physical pages leading to OOB read and/or write due to improper validation of the said value.
Such crafted log2 page size could lead to 4K pages being treated as higher order pages and allowing read and/or write access to the memory beyond 4K threshold.
Weakness: CWE-1284
