Overview

CVE-2026-68177 is a high-severity vulnerability. It was published on August 10, 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:

tracing: Delay module ref count for "enable_event" trigger

Triggers are now delayed from freeing, but can still be triggered until

after the RCU grace period has ended. The freeing of the enable_event data

is put into the private_data_free() callback, but the put of the module

refcount is done immediately.

It is possible that if a module is removed that has an event that would

enable (or disable) it is still active, it can read the data of the module

after it is removed causing a use-after-free bug.

Move the trace_event_put_ref() that releases the module into the delayed

callback so that the module can not be removed until any reference to its

events are finished.

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.
