A flaw was found in the Linux kernel's drm/hyperv component. A malicious Hyper-V guest could exploit an out-of-bounds memory access vulnerability by sending a crafted resolution response. This could potentially lead to information disclosure or a denial of service. Additionally, an issue with the resolution probe fallback mechanism could prevent display functionality from initializing correctly, resulting in a denial of service.
