In the Linux kernel, the following vulnerability has been resolved:
drivers/perf: hisi: hns3: 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 HNS3_PMU_MAX_HW_EVENTS, 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/}
