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...

CVE-2026-52980

The CVE-2026-52980 issue affects the Linux kernel’s CFS scheduler: when forking a task, rel_deadline may be inherited in sched_entity, causing a relative deadline to be treated as absolute during the first enqueue. This leads to an inflated vruntime after yield_task_fair(), potential overflow of ...
