CVE-2023-0185

Host service interruption or disclosure via sign conversion

Published Apr 1, 2023 · Updated Feb 13, 2025

Sign-conversion error in NVIDIA Virtual GPU Manager allows local users with high privileges to disclose limited data or interrupt host service. The Linux kernel-mode layer casts an unsigned primitive to a signed value, so values outside the signed range are misinterpreted. Exploitation requires high local privileges and complex conditions; NVIDIA does not disclose whether denial of service hangs or crashes the host.
