CVE-2026-97965

A flaw was found in the Linux kernel's Virtual Extensible LAN VXLAN driver. When transmitting network packets on devices configured with Group Based Policy GBP metadata, the driver fails to properly initialize an internal stack variable if packet flags are omitted. This issue allows residual kern...

CVE-2026-98023

A flaw was found in the Linux kernel's Virtual Extensible LAN VXLAN driver. A local user with network administration privileges can cause a Denial of Service DoS by configuring dynamic forwarding database FDB entries that reference a shared next-hop group across multiple devices. This improper...

CVE-2026-98122

A flaw was found in the Linux kernel's Virtual Extensible LAN VXLAN driver. A local unprivileged attacker can cause a denial of service DoS or potentially escalate privileges through memory corruption. This vulnerability occurs because the Multicast Database MDB subsystem improperly validates...
