It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service excessive CPU consumption. CVE-2023-1206 Daniel Trujillo, Johannes Wikner, and Kaveh Razavi...

CVE-2023-4809

In pf packet processing with a 'scrub fragment reassemble' rule, a packet containing multiple IPv6 fragment headers would be reassembled, and then immediately processed. That is, a packet with multiple fragment extension headers would not be recognized as the correct ultimate payload. Instead a...

OESA-2023-1586 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when a user makes a new kind of SYN flood attack. A user located in the local network or with a high bandwidth connectio...

A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when a user makes a new kind of SYN flood attack. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6...

Important: kernel

Issue Overview: An issue was found in the Linux kernel's IPv6 TCP connection tracking code, which could lead to high CPU usage with certain traffic patterns. CVE-2023-1206 Affected Packages: kernel Note: This advisory is applicable to Amazon Linux 2 - Kernel-5.15 Extra. Visit this page to learn...

UBUNTU-CVE-2023-3022

A flaw was found in the IPv6 module of the Linux kernel. The arg.result was not used consistently in fib6rulelookup, sometimes holding rt6info and other times fib6info. This was not accounted for in other parts of the code where rt6info was expected unconditionally, potentially leading to a kerne...
