Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> crypto: virtio - Add spinlock protection with virtqueue notification<br /> <br /> When VM boots with one virtio-crypto PCI device and builtin backend,<br /> run openssl benchmark command with multiple processes, such as<br /> openssl speed -evp aes-128-cbc -engine afalg -seconds 10 -multi 32<br /> <br /> openssl processes will hangup and there is error reported like this:<br /> virtio_crypto virtio0: dataq.0:id 3 is not a head!<br /> <br /> It seems that the data virtqueue need protection when it is handled<br /> for virtio done notification. If the spinlock protection is added<br /> in virtcrypto_done_task(), openssl benchmark with multiple processes<br /> works well.
