scsi: bfa: integer overflow in debugfs
[ Upstream commit 3e351275 ] We could allocate less memory than intended because we do: bfad->regdata = kzalloc(len << 2, GFP_KERNEL); The shift can overflow leading to a crash. This is debugfs code so the impact is very small. I fixed the network version of this in March with commit 13e2d518 ("bna: integer overflow bug in debugfs").
