一、漏洞信息
漏洞编号：CVE-2023-39192
漏洞归属组件：kernel
漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.0,6.1.14,6.1.19,6.1.5,6.1.6,6.1.8,6.4.0
CVSS V3.0分值：
BaseScore：6.0 Medium
Vector：CVSS：3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:H
漏洞简述：
A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds read by setting the size fields with a value beyond the array boundaries, leading to a crash or information disclosure.
