GHSA-WPX2-5M46-33QP

Vulnerability from github – Published: 2025-09-23 06:30 – Updated: 2025-12-12 21:31

Details

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

drm/mediatek: fix potential OF node use-after-free

The for_each_child_of_node() helper drops the reference it takes to each node as it iterates over children and an explicit of_node_put() is only needed when exiting the loop early.

Drop the recently introduced bogus additional reference count decrement at each iteration that could potentially lead to a use-after-free.

Severity ?

7.8 (High)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
