CVE-2024-43705

Protected-file overwrite via GPU memory wrapping

Published Dec 28, 2024 · Updated Dec 28, 2024

Improper permission handling in Imagination Technologies Graphics DDK 1.13 RTM through 24.2 RTM2 allows local users to overwrite read-only files. PVRSRVBridgePhysmemWrapExtMem lets the GPU kernel driver write into read-only system files, such as libc.so, when those files are mapped into application memory. A non-privileged application with access to the affected GPU driver can corrupt protected file-backed memory and the processes that use it.
