+Subject: [PATCH] vmw_pvscsi: check message ring page count at initialisation
+
+A guest could set the message ring page count to zero, resulting in
+infinite loop. Add check to avoid it.

+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.

+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

+
+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.
