CVE-2022-49835 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: fix potential memleak in 'add_widget_node' As 'kobject_add' may allocated memory for 'kobject->name' when return error. And in this function, if call 'kobject_add' failed didn't free kobject. So call 'kobject_put' to recycling resources.
A memory leak vulnerability has been identified in the Linux kernel's Advanced Linux Sound Architecture (ALSA) HD Audio (HDA) subsystem. The issue arises in the 'add_widget_node' function, where the 'kobject_add' call can allocate memory for the 'kobject->name' if an error occurs. If 'kobject_add' fails, the allocated memory is not freed, leading to a potential memory leak. The vulnerability has been addressed by ensuring that resources are properly recycled when 'kobject_add' fails.
