CVE-2026-74701 net/openvswitch: check Ethernet header length in key_extract()

In the Linux kernel, the following vulnerability has been resolved: net/openvswitch: check Ethernet header length in keyextract When a packet arrives on an ARPHRDNONE device e.g. TUN, ovsflowkeyextract trusts the user-provided skb-protocol field: if it is ETHPTEB, the packet is classified as...

EUVD-2026-64351

In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: reallocate update replies for mismatched IDs ovsflowcmdnew preallocates the optional reply skb before it takes ovsmutex and before it knows which existing flow will be updated.

CVE-2026-74664

This vulnerability affects the Linux kernel's Open vSwitch (OVS) netlink flow command handling. The root cause is in ovs_flow_cmd_new(), which preallocates the reply skb sized from the request flow identifier. When a flow update request uses a UFID that misses the UFID lookup and falls back to th...
