Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
media: max9286: Fix memleak in max9286_v4l2_register()
There is a kmemleak when testing the media/i2c/max9286.c with bpf mock device:
kmemleak: 5 new suspected memory leaks (see /sys/kernel/debug/kmemleak)

max9286_v4l2_register() calls v4l2_ctrl_new_std(), but won't free the created v412_ctrl when fwnode_graph_get_endpoint_by_id() failed, which causes the memleak. Call v4l2_ctrl_handler_free() to free the v412_ctrl.
