Christey" <coley@...us.mitre.org> Subject: CVE request: kernel: soft lockup occurs when network load is very high Steve, can you please assign a CVE name for the following issue: "[NET]: Add preemption point in qdisc_run The qdisc_run loop is currently unbounded and runs entirely in a softirq. This is bad as it may create an unbounded softirq run. This patch fixes this by calling need_resched and breaking out if necessary. It also adds a break out if the jiffies value changes since that would indicate we've been transmitting for too long which starves other softirqs." Problem is fixed upstream since 2ba2506ca7ca62c56edaa334b0fe61eb5eab6ab0 Reference: https://bugzilla.redhat.com/show_bug.cgi?id=477744 Reproducer: https://bugzilla.redhat.com/attachment.cgi?id=327745 This can be triggered by an unprivileged user. Thanks, Eugene
