kernel/sched/fair.c in the Linux kernel before 5.3.9, when cpu.cfs_quota_us
is used (e.g., with Kubernetes), allows attackers to cause a denial of
service against non-cpu-bound applications by generating a workload that
triggers unwanted slice expiration, aka CID-de53fd7aedb1. (In other words,
although this slice expiration would typically be seen with benign
workloads, it is possible that an attacker could calculate how many stray
requests are required to force an entire Kubernetes cluster into a
low-performance state caused by slice expiration, and ensure that a DDoS
attack sent that number of stray requests. An attack does not affect the
stability of the kernel; it only causes mismanagement of application
execution.)
