CVE-2022-49527

Summary

In the Linux kernel, the following vulnerability has been resolved:

media: venus: hfi: avoid null dereference in deinit

If venus_probe fails at pm_runtime_put_sync the error handling first calls hfi_destroy and afterwards hfi_core_deinit. As hfi_destroy sets core->ops to NULL, hfi_core_deinit cannot call the core_deinit function anymore.

Avoid this null pointer derefence by skipping the call when necessary.
