CVE-2025-39851

CVE-2025-39851 relates to the Linux kernel VXLAN implementation. Affected scenario is when learning is enabled and an incoming packet attempts to refresh an FDB entry that points to an FDB nexthop group (not a remote destination). This could dereference a non-existent remote and trigger a NULL po...

CVE-2025-39850

CVE-2025-39850 affects the Linux kernel vxlan implementation. When the VXLAN device runs with the proxy option enabled, ARP/IPv6 Neighbor Solicitation can be spuriously suppressed if the remote host’s MAC is not behind the any remote. The root cause is dereferencing an FDB nexthop entry that may ...
