CVE-2026-49743

CVE-2026-49743 affects GPU driver workflows where, during workload submission, the reference count of an underlying synchronisation primitive tied to an exported fence is not properly incremented. This can allow a local attacker running under a non-privileged user to destroy the exported fence an...

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...
