CVE-2024-27401: firewire: nosy: ensure user_length is taken into account when fetching packet contents
In the Linux kernel, the following vulnerability has been resolved:
firewire: nosy: ensure userlength is taken into account when fetching packet contents
Ensure that packetbufferget respects the userlength provided. If the length of the head packet exceeds the userlength, packetbufferget will now return 0 to signify to the user that no data were read and a larger buffer size is required. Helps prevent user space overflows.
