| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel’s drm/mediatek component related to device tree node handling. Specifically, the
for each child of node() helper function incorrectly manages reference counts for device tree nodes. An unnecessary decrement in the reference count during iteration could lead to a use-after-free condition. This occurs because the helper function releases the reference to each node as it iterates, and an additional, incorrect decrement was introduced.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
