Overview

CVE-2024-46764 is a high-severity vulnerability. It was published on September 18, 2024 and has a CVSS 3.1 base score of 7.3 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.3, 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: add check for invalid name in btf_name_valid_section()

If the length of the name string is 1 and the value of name[0] is NULL

byte, an OOB vulnerability occurs in btf_name_valid_section() and the

return value is true, so the invalid name passes the check.

To solve this, you need to check if the first position is NULL byte and

if the first character is printable.

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.
