CVE-2026-45198

GPU firmware corruption via untrusted REE pointer

Published Aug 7, 2026 · Updated Aug 7, 2026

Untrusted pointer dereference in affected Imagination Technologies Graphics DDK releases allows local users to corrupt GPU firmware data. RGXFWIF_SYSINIT::sCorememDataStore passes a pointer from non-secure REE memory to firmware, which dereferences it while saving or restoring internal state between private and main memory. Exploitation requires control of the REE kernel on a TEE-enabled Linux or Android platform; affected releases are 1.17 RTM2, 1.18 RTM2, 23.2 RTM2, 24.2 RTM2, 25.1 RTM2 through 25.3 RTM, and 26.1 RTM1.
