CyberRota Analysis

AI-Generated

A vulnerability exists in software running as a non-privileged user that improperly handles GPU system calls, specifically during workload submissions involving exported fences from the GPU driver. This flaw can lead to use-after-free conditions due to incorrect reference counting of synchronization primitives, potentially allowing attackers to manipulate memory and execute arbitrary code. Organizations utilizing GPU-accelerated applications should prioritize addressing this vulnerability to mitigate the risk of exploitation.

Original NVD Description

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 underlying synchronisation primitive is not properly incremented. This can be exploited, by destroying the exported fence and prematurely release the underlying primitive, resulting in a potential use-after-free condition.
