CVE-2026-7763 (GCVE-0-2026-7763)

Title
Heap buffer overflow in morse.ko TIM IE processing
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 passive scanning, no authentication, association, or user interaction is required.

Title
Heap buffer overflow in dot11ah.ko S1G Capabilities IE processing
Summary
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 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.

Title
Out-of-bounds read in morse.ko Vendor IE processing
Summary
An out-of-bounds read vulnerability in the morse.ko HaLow Wi-Fi kernel driver in Morse Micro HaLowLink 2 software versions prior to 2.11.12 allows an unauthenticated attacker within radio range to disclose a small amount of kernel heap memory or cause a Denial of Service (kernel oops/panic) via a crafted 802.11ah beacon or probe response frame containing a malformed Vendor Information Element. The function morse_vendor_find_vendor_ie() does not validate the IE length against the expected structure size before its result is passed to morse_vendor_rx_caps_ops_ie() and morse_vendor_fill_sta_vendor_info(), which read at fixed offsets into the IE data. Because the length check only requires the IE to be longer than 3 bytes, an attacker can supply an undersized IE, causing a heap out-of-bounds read of up to 9 bytes. No authentication, association, or user interaction is required.

CVE-2026-7763 (GCVE-0-2026-7763)

Title
Heap buffer overflow in morse.ko TIM IE processing
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 passive scanning, no authentication, association, or user interaction is required.

CVE-2026-7762 (GCVE-0-2026-7762)

Title
Heap buffer overflow in dot11ah.ko S1G Capabilities IE processing
Summary
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 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.

Title
Out-of-bounds read in morse.ko Vendor IE processing
Summary
An out-of-bounds read vulnerability in the morse.ko HaLow Wi-Fi kernel driver in Morse Micro HaLowLink 2 software versions prior to 2.11.12 allows an unauthenticated attacker within radio range to disclose a small amount of kernel heap memory or cause a Denial of Service (kernel oops/panic) via a crafted 802.11ah beacon or probe response frame containing a malformed Vendor Information Element. The function morse_vendor_find_vendor_ie() does not validate the IE length against the expected structure size before its result is passed to morse_vendor_rx_caps_ops_ie() and morse_vendor_fill_sta_vendor_info(), which read at fixed offsets into the IE data. Because the length check only requires the IE to be longer than 3 bytes, an attacker can supply an undersized IE, causing a heap out-of-bounds read of up to 9 bytes. No authentication, association, or user interaction is required.
