Severity by source
AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N
Network-reachable but requires low-privilege auth and non-trivial conditions; no availability impact described; high confidentiality and integrity impact align with code execution and data tampering.

Lifecycle Timeline
2DescriptionCVE.org
NVIDIA OpenShell for Linux contains a vulnerability in its sandbox exec handler, where an attacker could cause an OS command injection. A successful exploit of this vulnerability might lead to code execution, information disclosure, and data tampering.
AnalysisAI
OS command injection in NVIDIA OpenShell for Linux's sandbox exec handler allows a low-privileged, network-accessible attacker to inject and execute arbitrary OS commands outside the intended sandbox boundary. All versions are affected per CPE data (cpe:2.3:a:nvidia:openshell:*:*:*:*:*:*:*:*), with confirmed potential impact spanning code execution, information disclosure, and data tampering. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a low-privilege authenticated session with access to the NVIDIA OpenShell sandbox exec handler over the network (AV:N, PR:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 6.8 (Medium) is consistent with the vector's AC:H and PR:L constraints, which meaningfully reduce exploitability relative to a trivially reachable unauthenticated injection. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Consult the NVIDIA product security advisory at https://github.com/NVIDIA/product-security/tree/main/2026/5872 for patch availability and exact fixed versions - no specific patched release version is confirmed in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
