CVE-2025-25178

Kernel memory corruption via zero-size external-memory wrap

Published Apr 4, 2025 · Updated Apr 15, 2025

Memory corruption in Imagination Technologies Graphics DDK 1.15 RTM through 24.3 RTM allows local users to corrupt kernel memory. The PhysmemWrapExtMem path accepts a zero uiSize in an improper GPU system call, and the kernel module mishandles that quantity while wrapping external memory. A non-privileged account must run installed software on a system using the affected PowerVR driver; the published consequence is kernel-memory corruption.
