NVIDIA has released a software update for its NVDebug tool, addressing three high-severity vulnerabilities (CVE-2025-23342, CVE-2025-23343, and CVE-2025-23344) that could allow attackers to execute code, escalate privileges, and tamper with data. Users are strongly advised to update to version 1.7.0 or later.
The most severe issue, CVE-2025-23342, carries a CVSS base score of 8.2 (High). According to NVIDIA, “The NVIDIA NVDebug tool contains a vulnerability that may allow an actor to gain access to a privileged account. A successful exploit of this vulnerability may lead to code execution, denial of service, escalation of privileges, information disclosure and data tampering.”
This vulnerability requires local privileges but could give attackers significant control once exploited, making it especially dangerous in shared or multi-user environments.
Another flaw, CVE-2025-23343, scored 7.6 (High), results from improper handling of file writes. NVIDIA explains that the bug “may allow an actor to write files to restricted components. A successful exploit of this vulnerability may lead to information disclosure, denial of service, and data tampering.”
Because the issue could let attackers overwrite sensitive system components, it creates a risk of persistent tampering with the debugging environment.
The third vulnerability, CVE-2025-23344, is rated 7.3 (High). NVIDIA notes that it “may allow an actor to run code on the platform host as a non-privileged user. A successful exploit of this vulnerability may lead to code execution, denial of service, escalation of privileges, information disclosure and data tampering.”
Although exploitation requires low privileges, the flaw provides a pathway for attackers to move laterally or escalate privileges once inside a system.
All versions of the NVDebug tool prior to 1.7.0 on x86_64 or arm64-SBSA architecture systems are affected. NVIDIA has released NVDebug 1.7.0 and later as the patched version.
