In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scmi: Validate SENSOR_UPDATE payload size SENSOR_UPDATE carries one or more sensor readings after the fixed notification header. The parser derives the expected reading count from the sensor description, but it did not verify that the received payload contains those entries before parsing them. Reject truncated update notifications before reading the variable array.
