CVE-2026-24183

Privilege escalation via improper privilege management

Published Aug 18, 2026 · Updated Aug 18, 2026

Improper privilege management in the user management component in NVIDIA Cumulus Linux 5.15 allows local users to gain privileges. NVIDIA has not disclosed the affected file, command, or code path; public records say only that the user management component handles privileges incorrectly for an unprivileged local user. Exploitation requires local access and low privileges, and the resulting elevated context can grant broad control over the affected host.
