Overview

CVE-2024-36918 is a high-severity vulnerability. It was published on May 30, 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:

bpf: Check bloom filter map value size

This patch adds a missing check to bloom filter creating, rejecting

values above KMALLOC_MAX_SIZE. This brings the bloom map in line with

many other map types.

The lack of this protection can cause kernel crashes for value sizes

that overflow int's. Such a crash was caught by syzkaller. The next

patch adds more guard-rails at a lower level.

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.
