CVE-2024-55639

Estado: ModificadaMedia (5.5)—

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.
