CVE-2026-49743

Software installed and run as a non-privileged user may conduct improper GPU system calls to manipulate the lifetimes of synchronisation objects in the kernel, leading to read/write UAFs. During workload submission involving a fence exported by the GPU driver, the reference count of the underlyin...

CVE-2026-49743

A Use-After-Free (UAF) vulnerability exists in the GPU DDK because the GPU driver fails to properly increment the reference count of an underlying synchronisation primitive during workload submission involving an exported fence. A non-privileged user can exploit this by destroying the exported fe...
