CVE-2026-65161 NVIDIA CVE debrief

Who should care

Defenders responsible for AIStore framework on Linux systems should assess exposure and potential impact of information disclosure. This includes operators, platform administrators, vulnerability management teams, and security teams who need to verify exposure, assess impact, and implement necessary mitigations to prevent potential information disclosure due to crafted absolute source paths in the Promote API.

Why it matters

CVE-2026-65161 allows unauthenticated remote attackers to potentially read files accessible to the target process, requiring defenders to verify exposure and assess impact.

• Potential information disclosure due to crafted absolute source path
• Verification of access controls for the Promote API
• Assessment of system exposure to unauthenticated remote attacks

Technical summary

NVIDIA AIStore for Linux contains a vulnerability in the Promote API where an unauthenticated remote attacker may read files accessible to the target process by supplying a crafted absolute source path. This vulnerability requires defenders to assess exposure and potential impact of information disclosure on AIStore framework deployments, focusing on Linux systems and verifying access controls for the Promote API. The technical impact is that an attacker could potentially access sensitive information, emphasizing the need for defenders to prioritize verifying exposure and assessing the feasibility of information disclosure.

Defensive priority

Defenders should prioritize verifying exposure of AIStore framework on Linux systems and assessing the feasibility of information disclosure.

Recommended defensive actions

• Verify exposure of AIStore framework on Linux systems
• Assess the feasibility of information disclosure
• Review and update access controls for the Promote API
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
