Overview

CVE-2024-46684 is a medium-severity vulnerability. It was published on September 13, 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:

binfmt_elf_fdpic: fix AUXV size calculation when ELF_HWCAP2 is defined

create_elf_fdpic_tables() does not correctly account the space for the

AUX vector when an architecture has ELF_HWCAP2 defined. Prior to the

commit 10e29251be0e ("binfmt_elf_fdpic: fix /proc/<pid>/auxv") it

resulted in the last entry of the AUX vector being set to zero, but with

that change it results in a kernel BUG.

Fix that by adding one to the number of AUXV entries (nitems) when

ELF_HWCAP2 is defined.

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.
