drm/panthor: fix firmware control interface bounds checks
In the Linux kernel, the following vulnerability has been resolved: drm/panthor: fix firmware control interface bounds checks panthor_init_cs_iface() and panthor_init_csg_iface() validate firmware control interface offsets with 32-bit arithmetic and the size of the host wrapper structures. The offsets are derived from firmware-provided strides, so the arithmetic can wrap before the bounds check, and the host wrapper size is not the size of the firmware control interface being mapped. Use 64-bit arithmetic for the computed offsets and validate against the actual firmware control interface structure sizes with subtraction-based bounds checks. Also validate that the shared section is large enough for the global control interface before using it.
