Описание
[REJECTED CVE] A vulnerability has been identified in the Linux kernel's drm/nouveau/firmware module, where enabling SG_DEBUG causes a kernel BUG() in nvkm_firmware_ctor(). This occurs because DMA-allocated memory cannot be converted into memory pages, leading to an invalid scatterlist mapping. An attacker with control over kernel parameters or device initialization could potentially trigger this bug, causing a system crash or denial of service.
