CVE-2026-46188
In the Linux kernel, the following vulnerability has been resolved: octeonepvf: add NULL check for napibuildskb napibuildskb can return NULL on allocation failure. In octepvfoqprocessrx, the result is used directly without a NULL check in both the single-buffer and multi-fragment paths, leading t...
CVE-2026-46123
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: virtiobt: clamp rx length before skbput virtbtrxwork calls skbputskb, len where len comes directly from virtqueuegetbuf with no validation against the buffer we posted to the device. The RX skb is allocated in...

CVE-2026-46207
The CVE-2026-46207 issue affects the Linux kernel’s vsock/virtio path, where non-linear skbs could fail to copy payloads to the vsockmon tap device due to iov_iter not being properly initialized. The fix standardizes handling for both linear and non-linear skbs by removing the linear/non-linear s...

CVE-2026-46188 octeon_ep_vf: add NULL check for napi_build_skb()
In the Linux kernel, the following vulnerability has been resolved: octeonepvf: add NULL check for napibuildskb napibuildskb can return NULL on allocation failure. In octepvfoqprocessrx, the result is used directly without a NULL check in both the single-buffer and multi-fragment paths, leading t...
CVE-2026-46188
CVE-2026-46188 affects the Linux kernel in the octeon_ep_vf driver. The vulnerability arises because napi_build_skb() can return NULL on allocation failure and __octep_vf_oq_process_rx() uses the result without checking for NULL in both the single-buffer and multi-fragment paths, causing a NULL p...

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...
