CVE-2024-42098

5.5 · MEDIUM
Published Jul 29, 2024 linux EPSS 0.21% (11th pctl)

Overview

CVE-2024-42098 is a medium-severity vulnerability affecting linux linux_kernel. It was published on July 29, 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:

crypto: ecdh - explicitly zeroize private_key

private_key is overwritten with the key parameter passed in by the

caller (if present), or alternatively a newly generated private key.

However, it is possible that the caller provides a key (or the newly

generated key) which is shorter than the previous key. In that

scenario, some key material from the previous key would not be

overwritten. The easiest solution is to explicitly zeroize the entire

private_key array first.

Note that this patch slightly changes the behavior of this function:

previously, if the ecc_gen_privkey failed, the old private_key would

remain. Now, the private_key is always zeroized. This behavior is

consistent with the case where params.key is set and ecc_is_key_valid

fails.

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.
