In the Linux kernel, the following vulnerability has been resolved:
ARM: zynq: Fix refcount leak in zynq_early_slcr_init
of_find_compatible_node() returns a node pointer with refcount incremented,
we should use of_node_put() on error path.
Add missing of_node_put() to avoid refcount leak.

CVE-2023-53818 [LOW] CWE-772 kernel: Kernel: A flaw in ARM Zynq could lead to system unavailability
kernel: Kernel: A flaw in ARM Zynq could lead to system unavailability
In the Linux kernel, the following vulnerability has been resolved:
ARM: zynq: Fix refcount leak in zynq_early_slcr_init
of_find_compatible_node() returns a node pointer with refcount incremented,
we should use of_node_put() on error path.
Add missing of_node_put() to avoid refcount leak.
A flaw was found in the Linux kernel. A local attacker could exploit a vulnerability in the ARM Zynq component, specifically within the zynq_early_slcr_init function. This flaw, a 'reference count leak,' means that system resources are not properly released, which can lead to resource exhaustion. Consequently, this could result in a Denial of Service (DoS), making the system unavailable to legitimate users.
