Description

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