The Cloudflare WARP client for Windows assigns loopback IPv4 addresses for the DNS Servers, since WARP acts as local DNS server that performs DNS queries in a secure manner, however, if a user is connected to WARP over an IPv6-capable network, te WARP client did not assign loopback IPv6 addresses...

CVE-2023-2754

CVE-2023-2754 describes a vulnerability in the Cloudflare WARP Windows client where DNS queries can be exposed on the local network. When connected over an IPv6-capable network, the WARP client does not assign loopback IPv6 addresses; instead, it uses Unique Local Addresses, which under certain c...

net ipv6 output_core.c has an information leak because of certain use of a hash

In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/outputcore.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses...

FreeBSD -- Remote denial of service in IPv6 fragment reassembly

Problem Description: Each fragment of an IPv6 packet contains a fragment header which specifies the offset of the fragment relative to the original packet, and each fragment specifies its length in the IPv6 header. When reassembling the packet, the kernel calculates the complete IPv6 payload...
