CVE-2025-23279 is a local privilege escalation vulnerability in the NVIDIA .run Installer for Linux and Solaris. The flaw is a race condition, specifically a time-of-check to time-of-use issue, in the installer's handling of temporary files and directories during privileged installation and upgrade operations. The installer performs elevated actions such as extracting driver components, compiling kernel modules, and moving files into protected system locations. Because access to temporary resources is not properly synchronized, a local attacker can predict, monitor, replace, or otherwise manipulate those resources before they are processed with elevated privileges. This can allow attacker-controlled content or filesystem redirection to influence privileged installer behavior and lead to arbitrary code execution as root.
