CVE-2021-3905

Описание

A memory leak was found in Open vSwitch (OVS) during userspace IP fragmentation processing. An attacker could use this flaw to potentially exhaust available memory by keeping sending packet fragments.

Отчет

Red Hat Enterprise Linux 7 provides the openvswitch package only through the unsupported Optional repository. Customers are advised to install Open vSwitch (OVS) from RHEL Fast Datapath instead. Red Hat OpenStack Platform deployments are not affected because they use OVS/OVN directly from the Fast Datapath channel. Any updates will be distributed through that channel.
