CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's handling of firmware control interface offsets in the drm/panthor module, where improper bounds checks can lead to arithmetic wrapping due to the use of 32-bit calculations. This flaw could potentially allow an attacker to exploit memory corruption issues, leading to unauthorized access or system instability. Organizations using Linux systems, particularly those relying on the drm/panthor module for graphics or display functionalities, should prioritize patching to mitigate potential risks.
Original NVD Description
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.
