Administrative memory corruption via unchecked buffer copy
Published Dec 26, 2021 · Updated Aug 4, 2024
Buffer overflow in affected NETGEAR router firmware allows local users with administrative privileges to cause memory corruption. NVD maps the flaw to an unchecked-size buffer copy, but NETGEAR has not disclosed the component, copied input, or failure mode. Affected firmware spans R6300v2 before 1.0.4.52, R6400 before 1.0.1.52, R6900 before 1.0.2.8, R7000 before 1.0.9.88, R7900 before 1.0.3.18, R8000 before 1.0.4.46, R7900P and R8000P before 1.4.1.50, RAX75 and RAX80 before 1.0.3.88, and WNR3500Lv2 before 1.2.0.62.
