Summary
In the Linux kernel, the following vulnerability has been resolved: inet_diag: Initialize pad field in struct inet_diag_req_v2 KMSAN reported uninit-value access in raw_lookup() [1]. Diag for raw sockets uses the pad field in struct inet_diag_req_v2 for the underlying protocol. This field corresponds to the sdiag_raw_protocol field in struct inet_diag_req_raw. inet_diag_get_exact_compat() converts inet_diag_req to inet_diag_req_v2, but leaves the pad field uninitialized. So the issue occurs when raw_lookup() accesses the sdiag_raw_protocol field. Fix this by initializing the pad field in inet_diag_get_exact_compat(). Also, do the same fix in inet_diag_dump_compat() to avoid the similar issue in the future.

Diag for raw\\nsockets uses the pad field in struct inet_diag_req_v2 for the\\nunderlying protocol. This field corresponds to the sdiag_raw_protocol\\nfield in struct inet_diag_req_raw.\\n\\ninet_diag_get_exact_compat() converts inet_diag_req to\\ninet_diag_req_v2, but leaves the pad field uninitialized. So the issue\\noccurs when raw_lookup() accesses the sdiag_raw_protocol field.\\n\\nFix this by initializing the pad field in\\ninet_diag_get_exact_compat().
