Linux Linux Kernel Memory Corruption

Description

In the Linux kernel, the following vulnerability has been resolved: drm/logicvc: Fix device node reference leak in logicvc_drm_config_parse() The logicvc_drm_config_parse() function calls of_get_child_by_name() to find the "layers" node but fails to release the reference, leading to a device node reference leak. Fix this by using the __free(device_node) cleanup attribute to automatic release the reference when the variable goes out of scope.

Analysis

Linux kernel drm/logicvc driver fails to release a device node reference in logicvc_drm_config_parse(), causing a reference leak that can exhaust kernel memory resources over time. The vulnerability affects all Linux kernel versions with the logicvc DRM driver enabled; it requires local access to trigger repeated calls to the vulnerable code path. …
