CVE-2026-34956: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') in Red Hat Fast Datapath for RHEL 7CVE-2026-34956 0 CVE-2026-34956 is a medium severity vulnerability affecting Red Hat Fast Datapath for RHEL 7, specifically in Open vSwitch when using conntrack flow with FTP helpers over the userspace datapath. The issue arises from a buffer copy operation without checking the input size, allowing a remote attacker to send an EPASV command longer than 255 characters. This causes a heap access error leading to a crash and denial of service. There are no known exploits in the wild. The vendor advisory does not confirm the availability of a patch or remediation.
