CVE-2026-74664 net: openvswitch: reallocate update replies for mismatched IDs

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. That is normally fine because the...

CVE-2026-74657

CVE-2026-74657 affects the Linux kernel IPv4 FIB netlink size calculation. The function fib_nlmsg_size() incorrectly estimates nexthop space by assuming all gateways are encoded as IPv4 RTA_GATEWAY attributes. However, IPv4 routes can carry IPv6 gateways , which are dumped as RTA_VIA by fib_nexth...
