Vulnerability details
A heap-based buffer overflow vulnerability in the dot11ah.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…
more
Remote Code Execution via a crafted 802.11ah beacon or probe response frame containing a malformed S1G Capabilities Information Element (IE element ID 0xD9). The function morse_dot11ah_find_s1g_caps_for_bssid() uses the IE length field directly as the size argument to memcpy without validating it against the 15-byte destination buffer. An attacker can supply up to 255 bytes, causing an overflow of up to 240 bytes of attacker-controlled data into adjacent kernel heap memory. The vulnerability is triggerable during normal scanning without authentication, association, or user interaction.
