Detailsinfo

A vulnerability was found in Linux Kernel up to 6.16-rc4 and classified as problematic. This issue affects the function xdp_linearize_page of the component virtio-net. The manipulation with an unknown input leads to a out-of-bounds vulnerability. Using CWE to declare the problem leads to CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. Impacted is confidentiality. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: virtio-net: ensure the received length does not exceed allocated size In xdp_linearize_page, when reading the following buffers from the ring, we forget to check the received length with the true allocate size. This can lead to an out-of-bound read. This commit adds that missing check.

The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2025-38375 since 04/16/2025. Technical details are known, but no exploit is available.
