Description
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: tcpm/tcpci_maxim: validate header NDO against RX_BYTE_CNT
A broken/malicious port can transmit a CRC-valid frame whose header
advertises up to seven data objects but whose body carries fewer than
that. Check for this, and rightfully reject the message, instead of
reading from uninitialized stack memory.
