Description


In the Linux kernel, the following vulnerability has been resolved:\nscsi: mpi3mr: Avoid memcpy field-spanning write WARNING\nWhen the 'storcli2 show' command is executed for eHBA-9600, mpi3mr driver\nprints this WARNING message:\nmemcpy: detected field-spanning write (size 128) of single field 'bsg_reply_buf->reply_buf' at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 (size 1)\nWARNING: CPU: 0 PID: 12760 at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 mpi3mr_bsg_request+0x6b12/0x7f10 [mpi3mr]\nThe cause of the WARN is 128 bytes memcpy to the 1 byte size array '__u8\nreplay_buf[1]' in the struct mpi3mr_bsg_in_reply_buf. The array is intended\nto be a flexible length array, so the WARN is a false positive.\nTo suppress the WARN, remove the constant number '1' from the array\ndeclaration and clarify that it has flexible length. Also, adjust the\nmemory allocation size to match the change.
