Subject: [PATCH] vmw_pvscsi: check message ring page count at initialisation
A guest could set the message ring page count to zero, resulting in

Subject: [PATCH] audio: release capture buffers
AUD_add_capture() allocates two buffers which are never released.
Add the missing calls to AUD_del_capture().
Impact: Allows vnc clients to exhaust host memory by repeatedly
starting and stopping audio capture.

Subject: [PATCH] input: limit kbd queue depth
Apply a limit to the number of items we accept into the keyboard queue.
Impact: Without this limit vnc clients can exhaust host memory by
sending keyboard events faster than qemu feeds them to the guest.

Subject: [PATCH] scsi: avoid an off-by-one error in megasas_mmio_write
While reading magic sequence(MFI_SEQ) in megasas_mmio_write,
an off-by-one error could occur as 's->adp_reset' index is not
reset after reading the last sequence.
