CVE-2021-20177

Published: 12 January 2021

A flaw was found in the Linux kernel's implementation of string matching within a packet. A privileged user (with root or CAP_NET_ADMIN) when inserting iptables rules could insert a rule which can panic the system. Kernel before kernel 5.5-rc1 is affected.

From the Ubuntu Security Team

It was discovered that the netfilter subsystem in the Linux kernel did not properly handle filter rules in some situations. A local attacker with the CAP_NET_ADMIN capability could use this to cause a denial of service.
