CVE-2026-65103 — NVIDIA AIStore for Linux contains a path traversal vulnerability in the target-side object rename...

NVIDIA AIStore for Linux contains a path traversal vulnerability in the target-side object rename handler, where an unauthenticated remote attacker could cause an improper limitation of a pathname to a restricted directory by submitting a crafted rename destination directly to an AIStore target, resulting in the arbitrary creation or overwrite of a file. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, information disclosure, data tampering, and denial of service.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.9% (30-day exploitation probability)+9
  • Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (NVIDIA AIStore framework).
  2. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
  3. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  4. Search available logs for exploit probes matching the vulnerability class (file handling), errors and authentication anomalies.

What should defenders know first?

CVE-2026-65103 is "NVIDIA AIStore for Linux contains a path traversal vulnerability in the target-side object rename...", rated High. It affects AIStore framework (NVIDIA); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 8.1 describes technical severity. EPSS 0.90% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
