Technical details
A use-after-free (UAF) vulnerability exists in the Imagination Technologies Graphics DDK kernel module. During workload submission involving a fence exported by the GPU driver, the reference count of the underlying synchronization primitive is not properly incremented. A local, non-privileged attacker can exploit this by destroying the exported fence to prematurely release the underlying primitive while it is still in use. This results in a read/write UAF condition in the kernel. The vulnerability is patched in versions 1.18 RTM2, 23.2 RTM2, and 26.1 RTM2.
