Overview

CVE-2024-43868 is a medium-severity vulnerability. It was published on August 21, 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:

riscv/purgatory: align riscv_kernel_entry

When alignment handling is delegated to the kernel, everything must be

word-aligned in purgatory, since the trap handler is then set to the

kexec one. Without the alignment, hitting the exception would

ultimately crash. On other occasions, the kernel's handler would take

care of exceptions.

This has been tested on a JH7110 SoC with oreboot and its SBI delegating

unaligned access exceptions and the kernel configured to handle them.

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.
