CVE-2022-49462

The CVE-2022-49462 issue affects the Linux kernel DRM MSM A6xx driver (a6xx_gpu_init). Root cause: of_parse_phandle() returns a node pointer with refcount incremented and a missing of_node_put() leads to a refcount leak. The code path in a6xx_gmu_init() passes the node to of_find_device_by_node()...
