openvswitch security update
安全等级: High
公告ID: KylinSec-SA-2024-2372
发布日期: 2024年4月12日
关联CVE: CVE-2022-2639
Open vSwitch is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license.
Security Fix(es):
An 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)
