OpenStack Neutron allows remote attackers to bypass an intended ICMPv6-spoofing protection mechanism

The IPTables firewall in OpenStack Neutron before 7.0.4 and 8.0.0 through 8.1.0 allows remote attackers to bypass an intended ICMPv6-spoofing protection mechanism and consequently cause a denial of service or intercept network traffic via a link-local source address...

The vulnerability of the `icmp6_send_response_with_addrs_and_netif()` function in the implementation of the TCP/IP protocol lwIP allows a attacker to gain access to confidential data.

The vulnerability of the icmp6sendresponsewithaddrsandnetif function in the TCP/IP protocol implementation of the lwIP stack is related to the copying of buffers without checking the input data. Exploiting this vulnerability allows a remote attacker to gain access to confidential data through a...

USN-5362-1: Linux kernel (Intel IOTG) vulnerabilities

Nick Gregory discovered that the Linux kernel incorrectly handled network offload functionality. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. CVE-2022-25636 Enrico Barberis, Pietro Frigo, Marius Muench, Herbert Bos, and Cristiano Giuffrida...

USN-5346-1: Linux kernel (OEM) vulnerability

It was discovered that the ICMPv6 implementation in the Linux kernel did not properly deallocate memory in certain situations. A remote attacker could possibly use this to cause a denial of service memory exhaustion...
