NVIDIA has released a security update for its NVDebug tool to address three high-severity vulnerabilities that could allow an attacker to escalate privileges, execute code, and tamper with data.
The company is urging users to immediately install the latest version of the tool to protect their systems from potential exploitation.
The security advisory details three distinct flaws, the most critical of which is CVE-2025-23342, with a CVSS base score of 8.2.
This vulnerability, related to insufficiently protected credentials (CWE-522), could allow an attacker to gain access to a privileged account, leading to a complete system compromise.
The second flaw, CVE-2025-23343, is a path traversal vulnerability (CWE-22) with a CVSS score of 7.6.
A successful exploit could permit an attacker to write files to restricted parts of the file system, potentially leading to information disclosure, denial of service, or data tampering.
The third vulnerability, CVE-2025-23344, is an OS command injection flaw (CWE-78) rated at 7.3. This issue could allow a non-privileged user to run arbitrary code on the host machine, providing a direct method for escalating privileges.
The combination of these vulnerabilities poses a significant threat to affected systems. Privilege escalation is a primary concern, as it would allow an attacker with limited access to gain full administrative or root-level control.
Once an attacker has elevated privileges, they can perform a wide range of malicious actions, including installing malware, exfiltrating sensitive data, or establishing a persistent foothold within the network.
The potential for code execution further amplifies the risk, giving an attacker the ability to run any command or malicious payload on the compromised machine.
NVIDIA has noted that its risk assessment is based on an average across diverse systems and recommends that users evaluate the risk specific to their own configuration and environment.
Mitigations
These vulnerabilities impact all versions of the NVIDIA NVDebug tool prior to version 1.7.0. The affected tool runs on systems with x86_64 or arm64-SBSA architectures.
To remediate these security risks, NVIDIA has released a patched version of the software. The only recommended mitigation is to update the tool to version 1.7.0 or later.
Administrators and developers who use the NVDebug tool should download and install the latest version from the official NVIDIA Developer Tools page as soon as possible.
Promptly applying this update is essential to prevent attackers from leveraging these high-severity flaws to compromise systems.
