## Overview

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

accel/ivpu: Add bounds checks for firmware log indices

Add validation that read and write indices in the firmware log buffer
are within valid bounds (< data_size) before using them. If
out-of-bounds indices are encountered (from firmware), clamp them to
safe values instead of proceeding with invalid offsets.

This prevents potential out-of-bounds buffer access when firmware
supplies invalid log indices.

## Affected

- `linux_kernel >= 6.12.30, < 6.12.94`
- `linux_kernel >= 6.13, < 6.18.36`
- `linux_kernel >= 6.19, < 7.0.13`
- `linux_kernel = 7.1`

## Remediation

Upgrade past the affected range:

- `linux_kernel 7.0.13`
