CVE-2022-50065
Linux Kernel Virtio Net Memory Leak
Description

In the Linux kernel, the following vulnerability has been resolved: virtio_net: fix memory leak inside XPD_TX with mergeable When we call xdp_convert_buff_to_frame() to get xdpf, if it returns NULL, we should check if xdp_page was allocated by xdp_linearize_page(). If it is newly allocated, it should be freed here alone. Just like any other "goto err_xdp".
