Description
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Validate BASE_ERROR_EVENT payload size
BASE_ERROR_EVENT carries a variable number of message reports,
with the count encoded in error_status. The notification parser used
that count without checking whether the received payload contained all
reported entries.
Reject truncated payloads before copying the report array.
