Descriptions
In the Linux kernel, the following vulnerability has been resolved:
drivers/perf: hisi_pcie: Fix out-of-bound access when valid event group
The perf tool allows users to create event groups through following
cmd [1], but the driver does not check whether the array index is out of
bounds when writing data to the event_group array. If the number of events
in an event_group is greater than HISI_PCIE_MAX_COUNTERS, the memory write
overflow of event_group array occurs.
Add array index check to fix the possible array out of bounds violation,
and return directly when write new events are written to array bounds.
There are 9 different events in an event_group.
[1] perf stat -e '{pmu/event1/, ... ,pmu/event9/}'
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drivers/perf: hisi_pcie: corrige el acceso fuera de los límites cuando el grupo de eventos es válido. La herramienta perf permite a los usuarios crear grupos de eventos mediante el siguiente cmd [1], pero el controlador no compruebe si el índice de la matriz está fuera de los límites al escribir datos en la matriz event_group. Si el número de eventos en un event_group es mayor que HISI_PCIE_MAX_COUNTERS, se produce un desbordamiento de escritura en la memoria de la matriz event_group. Agregue la verificación del índice de la matriz para corregir la posible infracción de la matriz fuera de los límites y regrese directamente cuando se escriban nuevos eventos en los límites de la matriz. Hay 9 eventos diferentes en un grupo de eventos. [1] estadística de rendimiento -e '{pmu/event1/, ...,pmu/event9/}'
