What to do

AI-suggested

A fix has been implemented in the Linux kernel to check the index for aux_rd_interval before use, resolving the buffer overrun and integer overflow issues. Users should update to the latest Linux kernel versions containing this fix. Since this is a kernel-level vulnerability, applying the official kernel update is the recommended mitigation.

Description

A vulnerability in the Linux kernel's AMD display driver was fixed by adding bounds checking on the aux_rd_interval index. The aux_rd_interval array has a size of 7, and previously the index was not properly checked, leading to three buffer overrun and one integer overflow issues identified by Coverity. This flaw could potentially cause memory corruption if exploited.
