Summary
openvswitch vulnerabilities
Details

Timothy Redaelli and Haresh Khandelwal discovered that Open vSwitch incorrectly handled certain crafted Geneve packets when hardware offloading via the netlink path is enabled. A remote attacker could possibly use this issue to cause Open vSwitch to crash, leading to a denial of service. (CVE-2023-3966)

It was discovered that Open vSwitch incorrectly handled certain ICMPv6 Neighbor Advertisement packets. A remote attacker could possibly use this issue to redirect traffic to arbitrary IP addresses. (CVE-2023-5366)
