Description

sched/task_stack: fix object_is_on_stack() for KASAN tagged pointers

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

sched/task_stack: fix object_is_on_stack() for KASAN tagged pointers

When CONFIG_KASAN_SW_TAGS and CONFIG_KASAN_STACK are enabled, the

object_is_on_stack() function may produce incorrect results due to the

presence of tags in the obj pointer, while the stack pointer does not have

tags. This discrepancy can lead to incorrect stack object detection and

subsequently trigger warnings if CONFIG_DEBUG_OBJECTS is also enabled.

Example of the warning:

ODEBUG: object 3eff800082ea7bb0 is NOT on stack ffff800082ea0000, but annotated.
