In the Linux kernel, the following vulnerability has been resolved: sched/eevdf: Fix se->slice being set to U64_MAX and resulting crash There is a code path in dequeue_entities() that can set the slice of a sched_entity to U64_MAX, which sometimes results in a crash. The offending case is when dequeue_entities() is called to dequeue a delayed group entity, and then the entity's parent's dequeue is delayed. In that case: 1. In the if (entity_is_task(se)) else block at the beginning of dequeue_entities(), slice is set to cfs_rq_min_slice(group_cfs_rq(se)). If the entity was delayed, then it has no queued tasks, so cfs_rq_min_slice() returns U64_MAX. 2. The first for_each_sched_entity() loop dequeues the entity. 3. If the entity was its parent's only child, then the next iteratio
