kernel: soft lockup occurs when network load is very high

The qdiscrun function in net/sched/schgeneric.c in the Linux kernel before 2.6.25 on SMP machines allows local users to cause a denial of service soft lockup by sending a large amount of network traffic, as demonstrated by multiple simultaneous invocations of the Netperf benchmark application in...

Linux Kernel qdisc_run()本地拒绝服务漏洞

BUGTRAQ ID: 32985 CVECAN ID: CVE-2008-5713 Linux Kernel是开放源码操作系统Linux所使用的内核。 在多核（如16核）SMP机器上，如果并发的高流量的网络负载，就会导致内核中出现软锁定。 锁定出现在net/sched/schgeneric.c的84行的qdiscrun函数中。由于驱动持续发送报文并返回NETDEVTXOK，qdiscrun就无法退出qdiscrestart循环。尽管这可以提高吞吐能力，但某些应用程序可能被迟滞大约10秒钟。 Linux kernel 2.6.x Linux -----...

Linux Kernel 2.6.x - 'qdisc_run()' Local Denial of Service

/ source: https://www.securityfocus.com/bid/32985/info The Linux kernel is prone to a local denial-of-service vulnerability. Local attackers can exploit this issue to cause a soft lockup, denying service to legitimate users. Versions prior to Linux kernel 2.6.25 are vulnerable. / include include...

kernel: non-root can trigger cpu_idle soft lockup

Integer overflow in the hrtimerstart function in kernel/hrtimer.c in the Linux kernel before 2.6.23.10 allows local users to execute arbitrary code or cause a denial of service panic via a large relative timeout value. NOTE: some of these details are obtained from third party information...
