Overview

CVE-2024-27019 is a high-severity vulnerability. It was published on May 1, 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: Fix potential data-race in __nft_obj_type_get()

nft_unregister_obj() can concurrent with __nft_obj_type_get(),

and there is not any protection when iterate over nf_tables_objects

list in __nft_obj_type_get(). Therefore, there is potential data-race

of nf_tables_objects list entry.

Use list_for_each_entry_rcu() to iterate over nf_tables_objects

list in __nft_obj_type_get(), and use rcu_read_lock() in the caller

nft_obj_type_get() to protect the entire type query process.

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.
