Description OSIDB Bzimport 2026-10-23 11:55:04 UTC
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.
