In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix by adding FPU protection for dcn30internalvalidatebw Why Below general protection fault observed when WebGL Aquarium is run for longer duration. If drm debug logs are enabled and set to 0x1f then the issue is...

CVE-2021-47657 drm/virtio: Ensure that objs is not NULL in virtio_gpu_array_put_free()

In the Linux kernel, the following vulnerability has been resolved: drm/virtio: Ensure that objs is not NULL in virtiogpuarrayputfree If virtiogpuobjectshmeminit fails e.g. due to fault injection, as it happened in the bug report by syzbot, virtiogpuarrayputfree could be called with objs equal to...

CVE-2021-47657

CVE-2021-47657: In the Linux kernel, the vulnerability affects drm/virtio by risking a NULL pointer use in virtio_gpu_array_put_free() if virtio_gpu_object_shmem_init() fails. The problem arises when objs is NULL and virtio_gpu_array_put_free() is invoked. The fix is to ensure objs is not NULL in...
