CVE-2026-43392 sched_ext: Fix starvation of scx_enable() under fair-class saturation

In the Linux kernel, the following vulnerability has been resolved: schedext: Fix starvation of scxenable under fair-class saturation During scxenable, the READY - ENABLED task switching loop changes the calling thread's schedclass from fair to ext. Since fair has higher priority than ext,...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which arises from the possibility that scxenable may be infinitely starved during fair class saturation, leading to syst...
