Overview

CVE-2022-50234 is a high-severity vulnerability. It was published on September 15, 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:

io_uring/af_unix: defer registered files gc to io_uring release

Instead of putting io_uring's registered files in unix_gc() we want it

to be done by io_uring itself. The trick here is to consider io_uring

registered files for cycle detection but not actually putting them down.

Because io_uring can't register other ring instances, this will remove

all refs to the ring file triggering the ->release path and clean up

with io_ring_ctx_free().

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.
