CVE-2026-46123

Summary: CVE-2026-46123 affects the Linux kernel Bluetooth virtio_bt driver. The issue arises when virtbt_rx_work() skb_put(skb, len) uses an unvalidated len sourced from virtqueue_get_buf(), with the device exposing a 1000-byte RX buffer. Since alloc_skb() tailroom can exceed 1000, a malicious/b...
