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. (NVD)
