"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nARM: 9064/1: hw_breakpoint: Do not directly check the event's overflow_handler hook\n\nThe commit 1879445dfa7b (\"perf/core: Set event's default\n::overflow_handler()\") set a default event->overflow_handler in\nperf_event_alloc(), and replace the check event->overflow_handler with\nis_default_overflow_handler(), but one is missing.\n\nCurrently, the bp->overflow_handler can not be NULL. As a result,\nenable_single_step() is always not invoked.\n\nComments from Zhen Lei:\n\n https://patchwork.kernel.org/project/linux-arm-kernel/patch/20210207105934.2001-1-thunder.leizhen@huawei.com/"
