GHSA-JRGX-V33C-5F8G

Vulnerability from github – Published: 2025-06-18 12:30 – Updated: 2025-11-25 21:32

Details

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

drm/mcde: Fix refcount leak in mcde_dsi_bind

Every iteration of for_each_available_child_of_node() decrements the reference counter of the previous node. There is no decrement when break out from the loop and results in refcount leak. Add missing of_node_put() to fix this.

Severity ?

5.5 (Medium)
