Vulnerability from cnvd - Published: 2023-01-31

Title

Linux kernel拒绝服务漏洞（CNVD-2023-05410）

Description

Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel在6.1.6之前的版本中存在拒绝服务攻击漏洞。在受影响的Linux内核版本中，流量控制子系统中的NULL指针解引用错误允许无特权用户通过使用“tc qdisc”和“tc class”命令设置的精心设计的流量控制配置触发拒绝服务(系统崩溃)。这会影响net/ schedule /sch_api.c中的qdisc_graft。攻击者可利用该漏洞对目标有针对性的发起攻击，危害站点系统安全。

CVE-2022-47929 (GCVE-0-2022-47929)

Vulnerability from cvelistv5 – Published: 2023-01-17 00:00 – Updated: 2025-04-04 18:01

Summary

In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control configuration that is set up with "tc qdisc" and "tc class" commands. This affects qdisc_graft in net/sched/sch_api.c.

Severity
