Overview

CVE-2026-98112 is a high-severity vulnerability affecting linux linux_kernel. It was published on September 25, 2026 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:

ksmbd: fix listener task lifetime on netdev events

The listener thread exits when its listening socket is shutdown. The

netdevice notifier shuts down the socket before calling kthread_stop(), so

the task_struct can be freed before kthread_stop() gets its reference.

Create the listener in a stopped state and hold an extra task_struct

reference until kthread_stop_put() completes. Also stop and release

listeners before freeing their interface records during TCP teardown.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
