Overview

CVE-2023-52494 is a high-severity vulnerability. It was published on March 11, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, 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:

bus: mhi: host: Add alignment check for event ring read pointer

Though we do check the event ring read pointer by "is_valid_ring_ptr"

to make sure it is in the buffer range, but there is another risk the

pointer may be not aligned. Since we are expecting event ring elements

are 128 bits(struct mhi_ring_element) aligned, an unaligned read pointer

could lead to multiple issues like DoS or ring buffer memory corruption.

So add a alignment check for event ring read pointer.

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.
