skge: potential memory corruption in skge_get_regs()
[ Upstream commit 294c149a209c6196c2de85f512b52ef50f519949 ]
The "p" buffer is 0x4000 bytes long. B3_RI_WTO_R1 is 0x190. The value
of "regs->len" is in the 1-0x4000 range. The bug here is that
"regs->len - B3_RI_WTO_R1" can be a negative value which would lead to
memory corruption and an abrupt crash.
