CVE-2026-68336

A flaw was found in the Linux kernel's bonding module. When a system is booted with IPv6 disabled, the bonding module incorrectly attempts to send IPv6 Network Service NS packets. This leads to a null pointer dereference, which is an attempt to access uninitialized memory. The consequence of this...

CVE-2026-72761

The webhook URL validator in website/notifications/webhooks.py uses ip.isglobal to reject non-public addresses after DNS resolution. IPv6 transition addresses NAT64 64:ff9b::/96, 6to4 2002::/16, Teredo 2001:0000::/32 are classified as globally routable by IANA, so isglobal returns True even when...
