Overview

CVE-2022-50355 is a high-severity vulnerability. It was published on September 17, 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:

staging: vt6655: fix some erroneous memory clean-up loops

In some initialization functions of this driver, memory is allocated with

'i' acting as an index variable and increasing from 0. The commit in

"Fixes" introduces some clean-up codes in case of allocation failure,

which free memory in reverse order with 'i' decreasing to 0. However,

there are some problems:

- The case i=0 is left out. Thus memory is leaked.

- In case memory allocation fails right from the start, the memory

freeing loops will start with i=-1 and invalid memory locations will

be accessed.

One of these loops has been fixed in commit c8ff91535880 ("staging:

vt6655: fix potential memory leak"). Fix the remaining erroneous loops.

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.

How can CyberStrike help with CVE-2022-50355?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2022-50355 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
