EDAC/versalnet: Fix device_node leak in mc_probe()

Published May 27, 2026 CVSS 3.1 · 5.5 Medium EPSS < 1% KEV · Not listed
Description
In the Linux kernel, the following vulnerability has been resolved:

EDAC/versalnet: Fix device_node leak in mc_probe()

of_parse_phandle() returns a device_node reference that must be released with
of_node_put(). The original code never freed r5_core_node on any exit path,
causing a memory leak.

Fix this by using the automatic cleanup attribute __free(device_node) which
ensures of_node_put() is called when the variable goes out of scope.
