Kernel service interruption via RGXCreateFreeList use-after-free
Published Jun 16, 2025 · Updated Jun 23, 2025
Use-after-free in Imagination Technologies Graphics DDK 1.15 RTM through 24.2 RTM2 allows physically proximate attackers to cause kernel exceptions. The RGXCreateFreeList error path mishandles a PMR_WriteBytes failure, frees a kernel-heap allocation, and subsequently reads from and writes to that freed memory. Public records do not explain how attackers induce the failure; the bounded consequence is a kernel exception and associated service interruption.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
