Hence this is hardening against fault device, missprogramming\nor bus corruption."

"value": "AV:L - The vulnerable code is reached only via local sysfs reads of IIO channel attributes (e.g. in_intensity_uva_raw), which require filesystem access on the target system; there is no network-facing kernel entry point.\nAC:L - An attacker with access to /dev/i2c-* can use I2C_SLAVE_FORCE and I2C_RDWR to program reserved IT values (5–7) into the sensor configuration register, then reliably trigger the out-of-bounds read with a normal sysfs read.\nPR:L - Triggering the bug requires only reading world-readable (0444) IIO sysfs attributes, which is available to an unprivileged local user on typical embedded/Linux deployments where /sys is accessible.\nUI:N - Exploitation requires no action by a separate victim; the attacker directly issues the sysfs read that invokes the vulnerable measurement path.\nS:U - Impact is confined to kernel driver behavior on the local system; there is no crossing of security boundaries such as VM escape, sandbox escape, or IOMMU bypass.\nC:H - The bug is an out-of-bounds read of kernel memory (up to 12 bytes past a static array in .rodata) when the integration-time index is 5, 6, or 7; per kernel scoring guidance, out-of-bounds reads are rated High unless strictly bounded, and the leaked value is not returned to userspace.\nI:N - The flaw is a read-only out-of-bounds array access; the out-of-bounds value is consumed only by msleep() and does not modify memory or enable arbitrary writes or code execution.\nA:H - An out-of-bounds integration-time value fed into msleep() can produce a very long uninterruptible sleep while the driver mutex is held, blocking all concurrent sensor reads and causing a denial of service on embedded/IoT systems that depend on the UV sensor."
