CVE-2022-49679
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
ARM: Fix refcount leak in axxia_boot_secondary
of_find_compatible_node() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. 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
