CyberRota Analysis
AI-GeneratedThe vulnerability in the Linux kernel affects the USB gadget MIDI2 implementation, where default configfs groups are not properly removed during teardown, leading to a memory leak. This can result in resource exhaustion over time, potentially impacting system stability and performance. Linux system administrators and developers utilizing the USB gadget MIDI2 functionality should prioritize addressing this issue to prevent potential degradation of system resources.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: midi2: remove default configfs groups on teardown f_midi2_alloc_inst() creates default configfs child groups for the default endpoint and default block using configfs_add_default_group(), setting their internal refcount to 1. However, during function teardown in f_midi2_free_inst() or EP cleanup in f_midi2_ep_opts_release(), configfs_remove_default_groups() is never called, therefore never dropping the refcount and leaking struct f_midi2_ep_opts and f_midi2_block_opts. Add the missing configfs_remove_default_groups() in the afformentioned functions to free the structs properly.
