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