CVE-2026-73585
MEDIUM 6.3A flaw was found in sblim-cmpi-base. Insecure temporary file creation in the provider registration scripts allows a local unprivileged user to perform a symlink attack. By creating a symlink in a world-writable directory, an attacker can redirect privileged writes to an arbitrary file during script execution in a privileged context. This can lead to the overwrite of root-owned files, potentially disrupting system services or operation. Exploitation is conditional on the script running with elevated privileges and may be mitigated by sticky-directory symlink protections.
No known exploitation, public exploit, or elevated probability at this time. Track for changes.
