一、漏洞信息
漏洞编号：CVE-2023-3611
漏洞归属组件：net
漏洞归属的版本：5.10
CVSS V3.0分值：
BaseScore：7.8 High

漏洞简述：
An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-of-bounds write because lmax is updated according to packet sizes without bounds checks. We recommend upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64.
