Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from an internal port object reference count that is not properly decremented, which could lead to a memory leak...

CVE-2022-50574 drm/omap: dss: Fix refcount leak bugs

In the Linux kernel, the following vulnerability has been resolved: drm/omap: dss: Fix refcount leak bugs In dssinitports and dssuninitports, we should call ofnodeput for the reference returned by ofgraphgetportbyid in fail path or when it is not used anymore...

CVE-2022-50574

Summary: CVE-2022-50574 concerns the Linux kernel driver chain for DRM/OMAP DSS where a refcount leak could occur. The root cause, as described, is missing calls to of_node_put() for the reference returned by of_graph_get_port_by_id() in fail paths or when the reference is no longer used. Impact ...

CVE-2025-39872

CVE-2025-39872 concerns the Linux kernel function hsr_get_port_ndev. The issue arises because hsr_get_port_ndev calls hsr_for_each_port and requires both the RCU lock and a device reference, but returning the port device without proper synchronization could yield use-after-free in the caller. The...
