Physical-memory access via duplicate freelist creation
Published Nov 30, 2024 · Updated Dec 1, 2024
Use-after-free in Imagination Technologies Graphics DDK 1.13 RTM through 24.2 RTM2 allows local users to read and write physical memory. Calling RGXCreateFreeList twice for the same reservation leaves the GPU using freed memory, enabling unauthorized access to physical pages. A nonprivileged application must issue the crafted GPU system calls; the documented consequence is physical-memory disclosure and modification.

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.
- Affected versionversion=1.13_rtm <=24.2_rtm2
- Affected versionversion=1.13 RTM <=24.2 RTM2
