Description
A flaw was found in the Linux kernel's ROHM BU27034 ambient light sensor driver. When reading the sensor integration time fails, the driver improperly uses the returned error code to calculate sleep duration. A local user interacting with the sensor interface during a read failure can cause the driver to enter an indefinite delay, leading to a denial of service (DoS) for the device.
