Description

In the Linux kernel, pick_next_rt_entity() may return a type confused entry, not detected by the BUG_ON condition, as the confused entry will not be NULL, but list_head.The buggy error condition would lead to a type confused entry with the list head,which would then be used as a type confused sched_rt_entity,causing memory corruption. A memory corruption flaw was found in the Linux kernel's scheduler subsystem. This could allow a local user to crash the system or potentially escalate their privileges on the system.
