Published Jul 30, 2024 linux CWE-476 EPSS 0.18% (8th pctl) CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Overview

CVE-2024-42151 is a medium-severity vulnerability affecting linux linux_kernel. It was published on July 30, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, 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: mark bpf_dummy_struct_ops.test_1 parameter as nullable

Test case dummy_st_ops/dummy_init_ret_value passes NULL as the first

parameter of the test_1() function. Mark this parameter as nullable to

make verifier aware of such possibility.

Otherwise, NULL check in the test_1() code:

SEC("struct_ops/test_1")

int BPF_PROG(test_1, struct bpf_dummy_ops_state *state)

{

if (!state)

return ...;

... access state ...

}

Might be removed by verifier, thus triggering NULL pointer dereference

under certain conditions.

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.
