The vulnerability in the implementation of the ICMPv6 protocol in the Linux operating system’s kernel, through the function fib6_add(), allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability in the implementation of the ICMPv6 protocol in the Linux operating system is related to the reutilization of previously freed memory due to competitive access to resources in the fib6add function within the net/ipv6/ip6fib.c module. Exploiting this vulnerability could allow a...

SUSE 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...
