CVE-2024-44556

Memory corruption via oversized IPTV VLAN input

Published Aug 26, 2024 · Updated Aug 26, 2024

Stack-based buffer overflow in Tenda AX1806 Firmware 1.0.0.1 allows attackers to corrupt memory via crafted adv.iptv.stballvlans input. An oversized adv.iptv.stballvlans value overruns a stack buffer in setIptvInfo and overwrites adjacent process memory. Public records disagree on whether exploitation is network-based and unauthenticated or local and low-privileged, and they do not establish code execution.
