NVIDIA Resiliency Extension for Linux contains a vulnerability in log aggregation, where an attacker could cause predictable log-file names. A successful exploit of this vulnerability may lead to escalation of privileges, code execution, denial of service, information disclosure, and data tampering.
Weakness
The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files.

Potential Mitigations
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
