Details

In the Linux kernel, the following vulnerability has been resolved:

net: sched: fix use-after-free in taprio_change()

In 'tapriochange()', 'admin' pointer may become dangling due to sched switch / removal caused by 'advancesched()', and critical section protected by 'q->currententrylock' is too small to prevent from such a scenario (which causes use-after-free detected by KASAN). Fix this by prefer 'rcureplacepointer()' over 'rcuassignpointer()' to update 'admin' immediately before an attempt to schedule freeing.
