Router software modification via stack buffer overflow
Published Jun 9, 2026 · Updated Jun 9, 2026
Stack-based buffer overflow in NETGEAR Orbi firmware allows remote authenticated users on the local network to alter router software. NETGEAR identifies insufficient validation of a stack buffer but has not disclosed the affected management endpoint, function, or copied field. Administrative credentials and adjacent-network access are required; exploitation permits unauthorized firmware or functionality changes, with no reported data disclosure or service interruption.
