一、漏洞信息
漏洞编号：CVE-2023-6816
漏洞归属组件：xorg-x11-server-xwayland
漏洞归属的版本：22.1.2
CVSS V3.0分值：
BaseScore：9.8 Critical
Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
漏洞简述：
A flaw was found in X.Org server. Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for each logical button currently down. Buttons can be arbitrarily mapped to any value up to 255, but the X.Org Server was only allocating space for the device s particular number of buttons, leading to a heap overflow if a bigger value was used.
