Description
A flaw was found in the `sched_ext` component of the Linux kernel. This vulnerability allows a local attacker to cause a system hang by exploiting an issue in the `scx_enable()` function. The function's task switching loop can lead to indefinite starvation of the enable thread when higher-priority fair-class workloads saturate the system. This results in a Denial of Service (DoS), making the system unresponsive.
