Physical-memory read and write via stale TLB mappings
Published Oct 14, 2024 · Updated Oct 15, 2024
Use-after-free in Imagination Technologies Graphics DDK 1.17 through 24.2 RTM1 allows local users to read and write freed GPU memory. A TLB invalidation race leaves physical pages from a dma_buf imported into multiple GPU devices accessible after the driver frees them. Non-privileged software with GPU system-call access can expose or corrupt physical memory; the vendor discloses no safe behavioral probe.

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=1.17 <=24.2 RTM1
- Affected versionversion=1.17 <=24.2rtmi
- Affected versionversion=24.2 RTM2
