CVE-2024-56544

A flaw was found in the Linux kernel's udmabuf driver. This vulnerability allows a local user to cause a denial of service (DoS) by requesting large buffer allocations. Because the driver relies on physically contiguous memory allocations with strict size limits, requesting buffers that exceed kernel page allocation boundaries fails and triggers kernel warnings.
