Overview

CVE-2022-49226 is a medium-severity vulnerability. It was published on February 26, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

Technical description

In the Linux kernel, the following vulnerability has been resolved:

net: asix: add proper error handling of usb read errors

Syzbot once again hit uninit value in asix driver. The problem still the

same -- asix_read_cmd() reads less bytes, than was requested by caller.

Since all read requests are performed via asix_read_cmd() let's catch

usb related error there and add __must_check notation to be sure all

callers actually check return value.

So, this patch adds sanity check inside asix_read_cmd(), that simply

checks if bytes read are not less, than was requested and adds missing

error handling of asix_read_cmd() all across the driver code.

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.
