CVE-2026-52980

A flaw was found in the Linux kernel's sched/fair scheduler. When a new schedentity is forked, its reldeadline may be unexpectedly set, leading to an abnormally large deadline value. If the task later calls schedyield, this inflated deadline can cause an overflow in vruntime calculations. This ca...
