CVE-2022-50194
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
soc: qcom: aoss: Fix refcount leak in qmp_cooling_devices_register
Every iteration of for_each_available_child_of_node() decrements the reference count of the previous node. When breaking early from a for_each_available_child_of_node() loop, we need to explicitly call of_node_put() on the child node. Add missing of_node_put() to avoid refcount leak.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
- Puntuación base: 5.5
