CVE-2026-41158

Arbitrary physical-page writes via deferred-free bypass

Published Jun 12, 2026 · Updated Jun 12, 2026

Use-after-free in Imagination Technologies Graphics DDK 25.1 through 26.1 RTM1 allows local users to write freed physical pages. Backed sparse physical memory resources bypass deferred freeing after shrink, so the GPU retains read and write access after the kernel module releases their pages. Local code must run as a non-privileged user with access to GPU system calls; successful writes can corrupt reclaimed physical memory.
