CVE-2022-49836

The CVE-2022-49836 issue in the Linux kernel concerns a memory leak in siox_device_add() if device_register() fails. The fix ensures proper reference handling: after an error, the name allocated by dev_set_name() is freed by freeing the reference with put_device(), allowing kobject_cleanup() to f...
