- Summary
- scsi: mpi3mr: Avoid memcpy field-spanning write WARNING
- Details
-
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 "bsgreplybuf->replybuf" at drivers/scsi/mpi3mr/mpi3mrapp.c:1658 (size 1) WARNING: CPU: 0 PID: 12760 at drivers/scsi/mpi3mr/mpi3mrapp.c:1658 mpi3mrbsg_request+0x6b12/0x7f10 [mpi3mr]
The cause of the WARN is 128 bytes memcpy to the 1 byte size array "_u8 replaybuf[1]" in the struct mpi3mrbsginreplybuf. 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.
