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()...

CVE-2022-49458

CVE-2022-49458 concerns the Linux kernel MSM DRM path where, if an error occurs before a request_irq() call, msm_drm_uninit() could call free_irq() on an IRQ that was not requested. The described backtrace shows a “Trying to free already-free IRQ” in a Qualcomm SM8350 environment, indicating a us...
