In the Linux kernel, the following vulnerability has been resolved: qede: sync udptunnel ports outside qedelock in the recovery path A TX timeout on a qede NIC that has VXLAN/GENEVE tunnel ports configured wedges the rtnetlink control plane of the whole machine: NETDEV WATCHDOG: ens6f1 qede:...

CVE-2026-74561

Summary: CVE-2026-74561 is a Linux kernel vulnerability where nh_rt_cache_flush walks an f6i_list without proper locking, racing with unlocked IPv6 route add/delete operations and freeing fib6_info. The fix migrates the sernum update to a broader netns scope by using rt_genid_bump_ipv6() instead ...

CVE-2026-74523

Summary: CVE-2026-74523 affects the Linux kernel qede driver with VXLAN/GENEVE tunnels. A TX timeout can cause recovery deadlocks in the driver’s mutex, freezing rtnetlink control for the node. What’s affected: The qede UDP tunnel synchronization flow during recovery paths, where recovery nested ...
