CVE-2023-3107

CVE-2023-3107 concerns a kernel vulnerability in FreeBSD involving IPv6 fragmentation reassembly. A crafted set of IPv6 fragments can trigger an integer overflow when computing the reassembled payload length, enabling a remote denial of service via a kernel panic. The issue affects multiple FreeB...

CVE-2023-3107 Remote denial of service in IPv6 fragment reassembly

A set of carefully crafted ipv6 packets can trigger an integer overflow in the calculation of a fragment reassembled packet's payload length field. This allows an attacker to trigger a kernel panic, resulting in a denial of service...

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...
