Description

This security bulletin contains information about 1 security vulnerability.


1) Resource exhaustion (CVE-ID: CVE-2023-52340)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to an error when processing very large ICMPv6 packets. A remote attacker can send a flood of IPv6 ICMP6 PTB messages, cause the high lock contention and increased CPU usage, leading to a denial of service.

Successful vulnerability exploitation requires a attacker to be on the local network or have a high bandwidth connection.
