Overview

CVE-2025-22074 is a high-severity vulnerability. It was published on April 16, 2025 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

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

ksmbd: fix r_count dec/increment mismatch

r_count is only increased when there is an oplock break wait,

so r_count inc/decrement are not paired. This can cause r_count

to become negative, which can lead to a problem where the ksmbd

thread does not terminate.

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.
