## Overview

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

ACPICA: Fix integer overflow in acpi_ex_opcode_3A_1T_1R() (mid_op)

Add overflow check for Index + Length to prevent integer overflow
when calculating the truncation length. This prevents negative
size parameter being passed to memcpy().

## Remediation

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