Description
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: tcpm: validate VDO count in Discover Identity ACK handlers
Properly validate the count passed from a device when calling
svdm_consume_identity() or svdm_consume_identity_sop_prime() as the
device-controlled value could index off of the static arrays, which
could leak data.
