virtio_net: fix device mismatch in devm_kzalloc/devm_kfree
ソース: NVD (National Vulnerability Database)
脆弱性説明
In the Linux kernel, the following vulnerability has been resolved: virtio_net: fix device mismatch in devm_kzalloc/devm_kfree Initial rss_hdr allocation uses virtio_device->device, but virtnet_set_queues() frees using net_device->device.
