could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2022-3239)

kernel: data races around icsk->icsk_af_ops in do_ipv6_setsockopt
A vulnerability, which was classified as problematic, was found in Linux Kernel. This affects the function tcp_getsockopt/tcp_setsockopt of the component TCP Handler. The manipulation leads to race condition. It is recommended to apply a patch to fix this issue. The identifier VDB-211089 was assigned to this vulnerability.
A vulnerability was found in the tcp subsystem in the Linux Kernel, due to a data race around icsk->icsk_af_ops. This issue could allow an attacker to leak internal kernel information.
Mitigation: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installa

CVE-2020-3566 [HIGH] CWE-400 Cisco IOS XR Software DVMRP Memory Exhaustion Vulnerability
Vulnerability: Cisco IOS XR Software DVMRP Memory Exhaustion Vulnerability
Affected: Cisco IOS XR
Cisco IOS XR Distance Vector Multicast Routing Protocol (DVMRP) incorrectly handles Internet Group Management Protocol (IGMP) packets. Exploitation could allow an unauthenticated, remote attacker to immediately crash the IGMP process or make it consume available memory and eventually crash.
Required Action: Apply updates per vendor instructions.
