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.
