CVE-2024-43701

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.
