CVE-2026-89725

CVE-2026-89725 affects the Linux kernel's STM32 CEC platform driver (media/cec/stm32). The root cause is an out-of-bounds write in stm32_rx_done(), which appends each received CEC byte to a fixed 16-byte buffer (CEC_MAX_MSG_SIZE) using rx_msg.len as an unchecked write index. Because the number of...
