漏洞简述：

In the Linux kernel, the following vulnerability has been resolved:perf/x86/amd: Fix crash due to race between amd_pmu_enable_all, perf NMI and throttlingamd_pmu_enable_all() does: if (!test_bit(idx, cpuc->active_mask)) continue; amd_pmu_enable_event(cpuc->events[idx]);A perf NMI of another event can come between these two steps. Perf NMIhandler internally disables and enables _all_ events, including the onewhich nmi-intercepted amd_pmu_enable_all() was in process of enabling.If that unintentionally enabled event has very low sampling period andcauses immediate successive NMI, causing the event to be throttled,cpuc->events[idx] and cpuc->active_mask gets cleared by x86_pmu_stop().This will result in amd_pmu_enable_event() getting called with event=NULLwhen amd_pmu_enable_all() resumes after handling the NMIs. This causes akernel crash: BUG: kernel NULL pointer dereference, address: 0000000000000198 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page [...] Call Trace: <TASK> amd_pmu_enable_all+0x68/0xb0 ctx_resched+0xd9/0x150 event_function+0xb8/0x130 ? hrtimer_start_range_ns+0x141/0x4a0 ? perf_duration_warn+0x30/0x30 remote_function+0x4d/0x60 __flush_smp_call_function_queue+0xc4/0x500 flush_smp_call_function_queue+0x11d/0x1b0 do_idle+0x18f/0x2d0 cpu_startup_entry+0x19/0x20 start_secondary+0x121/0x160 secondary_startup_64_no_verify+0xe5/0xeb </TASK>amd_pmu_disable_all()/amd_pmu_enable_all() calls inside perf NMI handlerwere recently added as part of BRS enablement but I m not sure whetherwe really need them.
