Linux GPU module flaws raise local security risks

What happened and what to do
On November 8, 2025, Quarkslab published an analysis of two bugs in open Linux kernel modules for NVIDIA GPUs. According to the post, a local unprivileged process can trigger them; a proof of concept demonstrates kernel read and write primitives.
Companies using these modules can identify exposed machines and workloads, prioritize available fixes, and restrict untrusted local processes. A monitored inventory, alerts for system changes, and access controls can help track exposure and reduce risk while remediation is planned.
How the consultancy can help
Wendelmaques can assess exposure across servers and workstations, define a remediation scope, and implement inventory, monitoring, and access controls, as well as support their ongoing operation.
