Description

A vulnerability was found in the Linux kernel's sched/eevdf code, specifically in the reweight_eevdf() function. The issue arises when the vlag variable overflows due to improper scaling in the computation, which leads to incorrect behavior in the vruntime. This causes a NULL dereference in the entity_eligible() function, potentially resulting in system crashes.
