CVE-2026-45201

Local physical-memory access via invalid page size

Published Aug 21, 2026 · Updated Aug 21, 2026

Out-of-bounds access in Imagination Technologies Graphics DDK allows local users to read or write arbitrary physical memory. PhysmemNewRamBackedPMR fails to validate a caller-supplied log2 page size, so a 4 KB page is handled as a higher-order allocation. A non-privileged local process can cross the 4 KB allocation boundary in 24.2 RTM2, 25.1 RTM2 through 25.3 RTM, and 26.1 RTM1.
