Details
In the Linux kernel, the following vulnerability has been resolved: soundwire: stream: fix memory leak in stream config error path When stream config is failed, master runtime will release all slave runtime in the slave_rt_list, but slave runtime is not added to the list at this time. This patch frees slave runtime in the config error path to fix the memory leak.
