EUVD-2026-32815

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...

EUVD-2026-32813

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: virtiobt: validate rx pkttype header length virtbtrxhandle reads the leading pkttype byte from the RX skb and forwards the remainder to hcirecvframe for every event/ACL/SCO/ISO type, without checking that the remaining...

CVE-2026-46163 wifi: b43legacy: enforce bounds check on firmware key index in RX path

In the Linux kernel, the following vulnerability has been resolved: wifi: b43legacy: enforce bounds check on firmware key index in RX path Same fix as b43: the firmware-controlled key index in b43legacyrx can exceed dev-maxnrkeys. The existing B43legacyWARNON is non-enforcing in production builds...

CVE-2026-46152

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: drop stray 'static' from fast-RX rxresult ieee80211invokefastrx is documented as safe for parallel RX, but its per-invocation rxresult is declared static. Concurrent callers then share one instance and can overwri...

CVE-2026-46145

The CVE-2026-46145 vulnerability affects the Linux kernel, specifically the RDMA/mana component. A user-supplied rx_hash_key_len value supplied via a uAPI structure is blindly passed to memcpy, enabling localized kernel memory corruption if bounds checks are not enforced. Reports from multiple so...

EUVD-2026-32882

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-2026-46123

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...

CVE-2026-46110

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: Prevent NULL deref when RX memory exhausted The CPU receives frames from the MAC through conventional DMA: the CPU allocates buffers for the MAC, then the MAC fills them and returns ownership to the CPU. For each...
