kernel: procfs: fix missing RCU protection when reading real_parent in do_task_stat()

A flaw was found in the Linux kernel's procfs component. When reading /proc/pid/stat, the dotaskstat function accesses task-realparent without proper Read-Copy-Update RCU protection. This missing protection creates a race condition, which can lead to a Use-After-Free UAF vulnerability. A local...
