CVE-2025-21703

一、漏洞信息
漏洞编号：CVE-2025-21703
漏洞归属组件：kernel
漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.19,6.1.8,6.4.0,6.6.0
CVSS V3.0分值：
BaseScore：7.8 High
Vector：CVSS：3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:netem: Update sch->q.qlen before qdisc_tree_reduce_backlog()qdisc_tree_reduce_backlog() notifies parent qdisc only if childqdisc becomes empty, therefore we need to reduce the backlog of thechild qdisc before calling it. Otherwise it would miss the opportunityto call cops->qlen_notify(), in the case of DRR, it resulted in UAFsince DRR uses ->qlen_notify() to maintain its active list.

In the Linux kernel, the following vulnerability has been resolved:

netem: Update sch->q.qlen before qdisc_tree_reduce_backlog()

qdisc_tree_reduce_backlog() notifies parent qdisc only if child
qdisc becomes empty, therefore we need to reduce the backlog of the
child qdisc before calling it. Otherwise it would miss the opportunity
to call cops->qlen_notify(), in the case of DRR, it resulted in UAF
since DRR uses ->qlen_notify() to maintain its active list.

The Linux kernel CVE team has assigned CVE-2025-21703 to this issue.
