Cisco is currently looking into its product line to determine which products and services use Linux kernel 3.9 or above, which is vulnerable to the FragmentSmack denial-of-service (DoS) bug.
The networking hardware manufacturer already assembled a list of more than 80 products that are affected by the vulnerability. Many of them expect a fix by February 2019.
The products currently under investigation are from the routing and switching category, designed for enterprises and service providers. More specifically, the company is looking at the Application Policy Infrastructure Controller Enterprise Module (APIC-EM).
