This is a single-patch series that adds bounds checking to firmware log indices (`read_index` and `write_index`) in the IVPU (Intel VPU accelerator) driver. The firmware writes these indices and the host reads them via `READ_ONCE()`, so they are an untrusted input boundary that should be validated. The fix is targeted at a real bug class — out-of-bounds buffer access from malicious or corrupted firmware data — and is appropriately tagged for stable backport.
The patch is **mostly correct** but has an **asymmetry in the boundary checks** that appears to be a bug, and there are some additional considerations worth discussing.
