NVDebug tool: Internal Asset Exposed to Unsafe Debug Access Level or State
CVE-2025-23252 is a high-severity internal asset exposed to unsafe debug access level or state vulnerability in NVDebug tool from NVIDIA, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected NVDebug tool versions: 1.6.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.34% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of NVDebug tool you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on nvidia.custhelp.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Internal Asset Exposed to Unsafe Debug Access Level or State
The product uses physical debug or test interfaces with support for multiple access levels, but it assigns the wrong debug access level to an internal asset, providing unintended access to the asset from untrusted debug agents.
How developers prevent this class of flaw
- For security-sensitive assets accessible over debug/test interfaces, only allow trusted agents.
- Apply blinding or masking techniques in strategic areas.
- Add shielding or tamper-resistant protections to the device, which increases the difficulty and cost for accessing debug/test interfaces.
