  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: mpi3mr: Avoid memcpy field-spanning write WARNING\n\nWhen the \"storcli2 show\" command is executed for eHBA-9600, mpi3mr driver\nprints this WARNING message:\n\n  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)\n  WARNING: CPU: 0 PID: 12760 at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 mpi3mr_bsg_request+0x6b12/0x7f10 [mpi3mr]\n\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.\n\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.",
