Overview

CVE-2024-26925 is a high-severity vulnerability. It was published on April 25, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_tables: release mutex after nft_gc_seq_end from abort path

The commit mutex should not be released during the critical section

between nft_gc_seq_begin() and nft_gc_seq_end(), otherwise, async GC

worker could collect expired objects and get the released commit lock

within the same GC sequence.

nf_tables_module_autoload() temporarily releases the mutex to load

module dependencies, then it goes back to replay the transaction again.

Move it at the end of the abort phase after nft_gc_seq_end() is called.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
