Overview

CVE-2025-23158 is a high-severity vulnerability. It was published on May 1, 2025 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:

media: venus: hfi: add check to handle incorrect queue size

qsize represents size of shared queued between driver and video

firmware. Firmware can modify this value to an invalid large value. In

such situation, empty_space will be bigger than the space actually

available. Since new_wr_idx is not checked, so the following code will

result in an OOB write.

...

qsize = qhdr->q_size

if (wr_idx >= rd_idx)

empty_space = qsize - (wr_idx - rd_idx)

....

if (new_wr_idx < qsize) {

memcpy(wr_ptr, packet, dwords << 2) --> OOB write

Add check to ensure qsize is within the allocated size while

reading and writing packets into the queue.

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.
