CVE-ID: CVE-2024-26643

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a race condition within the nf_tables_unbind_set() function in net/netfilter/nf_tables_api.c. A local user can exploit the race and escalate privileges on the system.

Mitigation

Install updates from vendor's repository.
