CVE-2023-0188

Service interruption via kernel-mode out-of-bounds read

Published Apr 1, 2023 · Updated Feb 13, 2025

Out-of-bounds read in NVIDIA vGPU Software 15.1 and earlier allows local users to interrupt service on affected Windows and Linux systems. The kernel-mode layer handler fails to restrict a memory-buffer operation to its allocated bounds and reads beyond the buffer. An unprivileged local account is required; exploitation is limited to an availability impact through service interruption.
