  "description": "Open vSwitch is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license.\r\n\r\nSecurity Fix(es):\r\n\r\nAn integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system.(CVE-2022-2639)",
