The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-986732 advisory.In the Linux kernel, the following vulnerability has been resolved:
soc: bcm: brcmstb: pm: pm-arm: Fix refcount leak in brcmstb_pm_probe
of_find_matching_node() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
In brcmstb_init_sram, it pass dn to of_address_to_resource(), of_address_to_resource() will call of_find_device_by_node() to take reference, so we should release the reference returned by of_find_matching_node().
Tenable has extracted the preceding description block directly from the Unity Linux security advisory.
