In the Linux kernel, the following vulnerability has been resolved:
ARM: 9064/1: hw_breakpoint: Do not directly check the event's overflow_handler hook
The commit 1879445dfa7b ("perf/core: Set event's default
::overflow_handler()") set a default event->overflow_handler in
perf_event_alloc(), and replace the check event->overflow_handler with
is_default_overflow_handler(), but one is missing.
Currently, the bp->overflow_handler can not be NULL. As a result,
enable_single_step() is always not invoked.
