Vulnerability from github – Published: 2025-06-18 12:30 – Updated: 2025-11-17 18:30

Details

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".

Severity ?

5.5 (Medium)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
