Jun 19, 2025 cve

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.
