CVE-2024-36920

In the Linux kernel, the following vulnerability has been resolved: scsi:
mpi3mr: Avoid memcpy field-spanning write WARNING When the “storcli2 show”
command is executed for eHBA-9600, mpi3mr driver prints this WARNING
message: memcpy: detected field-spanning write (size 128) of single field
“bsg_reply_buf->reply_buf” at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 (size

1. WARNING: CPU: 0 PID: 12760 at drivers/scsi/mpi3mr/mpi3mr_app.c:1658
   mpi3mr_bsg_request+0x6b12/0x7f10 [mpi3mr] The cause of the WARN is 128
   bytes memcpy to the 1 byte size array “__u8 replay_buf[1]” in the struct
   mpi3mr_bsg_in_reply_buf. The array is intended to be a flexible length
   array, so the WARN is a false positive. To suppress the WARN, remove the
   constant number ‘1’ from the array declaration and clarify that it has
   flexible length. Also, adjust the memory allocation size to match the
   change.
