CVE-2026-97436

A flaw was found in the Linux kernel's dpaa2-switch driver. When multiple network bridges are configured across ports on the same switch device, removing a port from a bridge fails to release its Forwarding Database (FDB), which tracks network destination addresses. A privileged user modifying network bridge configurations can trigger this condition, eventually forcing independent switch ports to share the same forwarding table. This issue may lead to improper network packet forwarding and unintended traffic exposure between isolated interfaces.
