Description

A flaw was found in the Linux kernel's AMD display (drm/amd/display) component. A local attacker could exploit an index out of bounds vulnerability within the cm_helper_translate_curve_to_degamma_hw_format function. This issue occurs when an index exceeds the expected number of transfer function points, potentially leading to a buffer overflow. Successful exploitation could result in a denial of service or, in some cases, arbitrary code execution, allowing the attacker to gain control over the system.
