Summary

A heap-based buffer overflow vulnerability in the morse.ko HaLow Wi-Fi kernel driver in Morse Micro HaLowLink 2 software versions prior to 2.11.13 allows an unauthenticated attacker within radio range to cause a Denial of Service (kernel panic) or potentially achieve Remote Code Execution via a crafted 802.11ah beacon frame containing a malformed Traffic Indication Map (TIM) Information Element. The function morse_page_slicing_process_tim_element() in page_slicing.c derives the TIM bitmap length directly from a received IE field without validating it against the fixed-size destination buffer before passing it to memset and memcpy operations, allowing up to 252 bytes of attacker-controlled data to be written beyond the buffer boundary. Because beacons are broadcast frames processed during p
