A vulnerability, which was classified as critical, was found in Netgear CBR750, D6220, D6400, D8500, LAX20, MK62, MR60, MS60, R6300v2, R6400, R6400v2, R6700v3, R6900P, R7000, R7000P, R7850, R7900, R7900P, R7960P, R8000, R8000P, RAX15, RAX20, RAX200, RAX35v2, RAX40v2, RAX43, RAX45, RAX50, RAX75, RAX80, RBK752, RBK852, RBR750, RBR850, RBS750, RBS850, RS400 and XR1000 (Wireless LAN Software). Affected is an unknown code. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability.
