CVE-2022-50065
Full vulnerability record from the local CVENow database.
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".

Al llamar a xdp_convert_buff_to_frame() para obtener xdpf, si devuelve NULL, debemos comprobar si xdp_page fue asignado por xdp_linearize_page(). Si es una asignación reciente, debe liberarse aquí únicamente. Al igual que con cualquier otro \"goto err_xdp\"."
