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.
