CVE-2016-6480 [MEDIUM] aacraid: Check size values after double-fetch from user
aacraid: Check size values after double-fetch from user
In aacraid's ioctl_send_fib() we do two fetches from userspace, one the
get the fib header's size and one for the fib itself. Later we use the
size field from the second fetch to further process the fib. If for some
reason the size from the second fetch is different than from the first
fix, we may encounter an out-of- bounds access in aac_fib_send(). We
also check the sender size to insure it is not out of bounds. This was
reported in https://bugzilla.kernel.org/show_bug.cgi?id=116751 and was
assigned CVE-2016-6480.

CVE-2016-6480 kernel: scsi: aacraid: double fetch in ioctl_send_fib()
The following flaw was found in the Linux kernel's aacraid driver:
I found this Double-Fetch bug in Linux-4.5/drivers/scsi/aacraid/commctrl.c when I was examining the source code.
In function ioctl_send_fib(), the driver fetches user space data by pointer arg via copy_from_user(), and this happens twice at line 81 and line 116 respectively. The first fetched value (stored in kfib) is used to get the header and calculate the size at line 90 so as to copy the whole message later at line 116, which means the copy size of the whole message is based on the old value that came from the first fetch. Besides, the whole message copied in the second fetch also contains the header.
However, when the function processes the messa
