Virtual GPU Manager: Out-of-bounds Read
CVE-2026-47535 is a high-severity out-of-bounds read vulnerability in Virtual GPU Manager from NVIDIA, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. Affected Virtual GPU Manager versions: 595.71.03(All versions prior to and including vGPU 20.1); 580.159.01(All versions prior to and including vGPU 19.5); 596.38(All versions prior to and including vGPU 20.1), and others listed below. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.13% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
