## Overview

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: Bound GPIO I2C table entry count from VBIOS

Reject undersized tables and cap the derived entry count
to AMDGPU_MAX_I2C_BUS so we do not overrun adev->i2c_bus[]
or walk an absurd number of entries on corrupt size fields.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
