CVE-2026-41154

Kernel memory read or write via index miscalculation

Published Jul 10, 2026 · Updated Jul 10, 2026

Out-of-bounds access in Imagination Technologies Graphics DDK allows local users to read or write kernel memory through GPU API calls. AllocOSPages_Sparse misindexes internal state while freeing sparse-memory pages larger than 4 kB, accessing beyond the kernel allocation. A non-privileged account must run crafted GPU API calls on 24.2 RTM2, 25.1 RTM2 through 25.3 RTM, or 26.1 RTM1; access can expose or corrupt kernel memory.
