CVE-2019-19922

A flaw was found in the Linux kernel’s scheduler, where it can allow attackers to cause a denial of service against non-CPU-bound applications by generating a workload that triggers unwanted scheduling slice expiration. A local attacker who can trigger a specific workload type could abuse this technique to trigger a system to be seen as degraded, and possibly trigger workload-rebalance in systems that use the slice-expiration metric as a measure of system health.

Mitigation

Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
