CVE-2025-38375 Information

Jul 26, 2025 cve

Description

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.
