Detailsinfo

A vulnerability classified as problematic was found in Linux Kernel up to 6.9.10. Affected by this vulnerability is the function dml2_calculate_rq_and_dlg_params of the component AMD Display. The manipulation with an unknown input leads to a array index vulnerability. The CWE definition for the vulnerability is CWE-129. The product uses untrusted input when calculating or using an array index, but the product does not validate or incorrectly validates the index to ensure the index references a valid position within the array. The impact remains unknown. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix array-index-out-of-bounds in dml2/FCLKChangeSupport [Why] Potential out of bounds access in dml2_calculate_rq_and_dlg_params() because the value of out_lowest_state_idx used as an index for FCLKChangeSupport array can be greater than 1. [How] Currently dml2 core specifies identical values for all FCLKChangeSupport elements. Always use index 0 in the condition to avoid out of bounds access.
