Description
A potential memory leak vulnerability in the Linux kernel's net: wwan: iosm component was fixed. The issue involved memory allocated in ipc_protocol_init() not being freed on error paths in ipc_imem_init(). The fix ensures that ipc_protocol_deinit() is called on error paths to release allocated memory.
