Summary

In the Linux kernel, the following vulnerability has been resolved:

net: wwan: iosm: fix potential memory leaks in ipc_imem_init()

The memory allocated in ipc_protocol_init() is not freed on the error paths that follow in ipc_imem_init(). Fix that by calling the corresponding release function ipc_protocol_deinit() in the error path.
