Aug 4 RESCORED — CVE-2024-55639 (Linux). CVSS 8.4 → 5.5 (NVD).
Description
In the Linux kernel, the following vulnerability has been resolved:
net: renesas: rswitch: avoid use-after-put for a device tree node
The device tree node saved in the rswitch_device structure is used at
several driver locations. So passing this node to of_node_put() after
the first use is wrong.
Move of_node_put() for this node to exit paths.
