CVE-2024-38662

4.7 · MEDIUM
Published Jun 21, 2024 linux EPSS 0.22% (13th pctl)

Overview

CVE-2024-38662 is a medium-severity vulnerability affecting linux linux_kernel. It was published on June 21, 2024 and has a CVSS 3.1 base score of 4.7 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.7, rated MEDIUM. 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: Allow delete from sockmap/sockhash only if update is allowed

We have seen an influx of syzkaller reports where a BPF program attached to

a tracepoint triggers a locking rule violation by performing a map_delete

on a sockmap/sockhash.

We don't intend to support this artificial use scenario. Extend the

existing verifier allowed-program-type check for updating sockmap/sockhash

to also cover deleting from a map.

From now on only BPF programs which were previously allowed to update

sockmap/sockhash can delete from these map types.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
