kernel: net: mana: validate rx_req_idx to prevent out-of-bounds array access

A flaw was found in the Linux kernel's mana network driver. In Confidential Virtual Machines VMs, a missing bounds check when processing network events can allow a malicious hardware component or a compromised VM to write data outside of an intended memory region. This out-of-bounds access could...
