Hello there all,
Has anyone else noticed the router logs (RV320/325) showing this a lot?

I have the same problem, did you ever find a resolution ?

This seems to be solved with the latest new update from March 2016 (1.3.x).

i am running firmware ver 1.2.1.14 . as a work around, i disabled the firewall which stopped the errors. this is not an option for most people but in my case client only had access points connected to the router for public wifi access for customers and firewall is not required. when i get time i will try loading the 1.3.x firmware.

The Cisco site does not have a March 2016 (1.3.x) Firmware for the RV320.

On my RV320 I'm running v1.3.1.12 (2016-04-27, 10:46:12)
I'm seeing this up to 5 times per day - is the root cause known?
Is there a fix?

Hello all, I found the following information. Basically the router is under a DDoS attack.
Below you will find additional information about the Linux kernel vulnerability that's being explode.

CVE-2017-18017 DetailMODIFIED This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided. Current DescriptionThe tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action.
