FKIE_CVE-2025-68265
Vulnerability from fkie_nvd - Published: 2025-12-16 15:15 - Updated: 2026-10-15 22:19
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme: fix admin request_queue lifetime
The namespaces can access the controller's admin request_queue, and
stale references on the namespaces may exist after tearing down the
controller. Ensure the admin request_queue is active by moving the
controller's 'put' to after all controller references have been released
to ensure no one is can access the request_queue. This fixes a reported
use-after-free bug:
