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...

CVE-2026-19186

An integer underflow vulnerability exists in the ieee802154_decipher_data_frame() function within subsys/net/l2/ieee802154/ieee802154_frame.c . The software fails to verify if a received frame is long enough before subtracting header and authentication tag lengths from the total length. Because t...
