In the Linux kernel, the following vulnerability has been resolved: virtio-net: fix len check in receive_big() receive_big() bounds the… (CVE-2026-64552)CVE-2026-64552 0 A vulnerability in the Linux kernel's virtio-net driver was resolved involving an incorrect length check in the receive_big() function. The function's bounds check for device-announced packet length was too loose, allowing a malicious virtio backend to specify a length that causes an out-of-bounds write past the static fragment array. This results in a NULL fragment being passed up the receive path, potentially leading to memory corruption. The issue was fixed by tightening the length bounds to match the actual buffer size advertised by add_recvbuf_big().
