CVE-2026-75085 Out-of-bounds read from received-frame length underflow in the STM32WBA IEEE 802.15.4 driver

The STM32WBA IEEE 802.15.4 driver in drivers/ieee802154/ieee802154stm32wba.c computed the packet length of a received frame as pktlen = rxframe-length - IEEE802154FCSLENGTH without first checking that the radio-reported length could hold an FCS. pktlen is a uint8t, so a reported length of 0 or 1...
