In the Linux kernel, the following vulnerability has been resolved: media: ov5675: Fix memleak in ov5675_init_controls() There is a kmemleak when testing the media/i2c/ov5675.c with bpf mock device: AssertionError: unreferenced object 0xffff888107362160 (size 16): comm "python3", pid 277, jiffies 4294832798 (age 20.722s) hex dump (first 16 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [] __kmalloc_node+0x44/0x1b0 [] kvmalloc_node+0x34/0x180 [] v4l2_ctrl_handler_init_class+0x11d/0x180 [videodev] [] ov5675_probe+0x38b/0x897 [ov5675] [] i2c_device_probe+0x28d/0x680 [] really_probe+0x17c/0x3f0 [] __driver_probe_device+0xe3/0x170 [] driver_probe_device+0x49/0x120 [] __device_attach_driver+0xf7/0x150 [] bus_for_each_drv+0x114/0x180 [] __device_attach+0x1e5/0x2d0 [] bus_probe_device+0x126/0x140 [] device_add+0x810/0x1130 [] i2c_new_client_device+0x386/0x540 [] of_i2c_register_device+0xf1/0x110 [] of_i2c_notify+0xfc/0x1f0 ov5675_init_controls() won't clean all the allocated resources in fail path, which may causes the memleaks. Add v4l2_ctrl_handler_free() to prevent memleak.
