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:

wifi: cfg80211: don't free driver-owned scan requests

When an interface goes down while a scan is running, cfg80211 completes

the scan towards userspace and frees the scan request. However, the

driver can be convinced that it owns the request, since the cancellation

is (intended to be) asynchronous.

The WARN_ON() in the netdev notifier was meant to catch this, but it's

not actually avoidable, so it triggers and we get a UAF in scan_done().

There doesn't seem to be a great way around it, so just track that the

driver is still convinced it owns the request, and then just free it on

completion if it was already cancelled. Also remove the warnings since

they can trigger in the intended architecture.

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-2026-98341?

CyberStrike is an open-source, AI-augmented pentesting engine.
