Overview

CVE-2022-50036 is a medium-severity vulnerability. It was published on June 18, 2025 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:

drm/sun4i: dsi: Prevent underflow when computing packet sizes

Currently, the packet overhead is subtracted using unsigned arithmetic.

With a short sync pulse, this could underflow and wrap around to near

the maximal u16 value. Fix this by using signed subtraction. The call to

max() will correctly handle any negative numbers that are produced.

Apply the same fix to the other timings, even though those subtractions

are less likely to underflow.

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.
