**Name of the Vulnerable Software and Affected Versions**
Yamaha RTX, RT, SRT, RTV, RTW, and RTA series routers versions 6.x through 10.x
NEC IP38X series routers versions 6.x through 10.x
**Description**
The issue is related to the improper handling of IP header options, which can be exploited by remote attackers to cause a denial of service. This is achieved by sending a crafted option that triggers access to an invalid memory location, resulting in a device reboot.
**Recommendations**
For Yamaha RTX, RT, SRT, RTV, RTW, and RTA series routers versions 6.x through 10.x, update the firmware to a version that properly handles IP header options.
For NEC IP38X series routers versions 6.x through 10.x, update the firmware to a version that properly handles IP header options.
As a temporary workaround, consider restricting access to the network to minimize the risk of exploitation.
