n the Linux kernel, the following vulnerability has been resolved: drivers/perf: Fix ali_drw_pmu driver interrupt status clearing The alibaba_uncore_pmu driver forgot to clear all interrupt status in the interrupt processing function. After the PMU counter overflow interrupt occurred, an interrupt storm occurred, causing the system to hang. Therefore, clear the correct interrupt status in the interrupt handling function to fix it.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drivers/perf: Fix ali_drw_pmu driver interval clearing El controlador alibaba_uncore_pmu olvidó borrar todos los estados de interrupción en la función de procesamiento de interrupciones. Después de que se produjo la interrupción por desbordamiento del contador de PMU, se produjo una tormenta de interrupciones, lo que provocó que el sistema se colgara. Por lo tanto, borre el estado de interrupción correcto en la función de manejo de interrupciones para solucionarlo.
