CVE-2021-47657 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:8.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-ipaclones-internal package and not the kernel-ipaclones-internal package as distributed by RHEL.
In the Linux kernel, the following vulnerability has been resolved:
drm/virtio: Ensure that objs is not NULL in virtio_gpu_array_put_free()
If virtio_gpu_object_shmem_init() fails (e.g. due to fault injection, as it happened in the bug report by syzbot), virtio_gpu_array_put_free() could be called with objs equal to NULL.
Ensure that objs is not NULL in virtio_gpu_array_put_free(), or otherwise return from the function.
