kernel: ip6_tunnel: clear skb2->cb[] in ip4ip6_err()
In the Linux kernel, the following vulnerability has been resolved: ip6tunnel: clear skb2-cb in ip4ip6err Oskar Kjos reported the following problem. ip4ip6err calls icmpsend on a cloned skb whose cb was written by the IPv6 receive path as struct inet6skbparm. icmpsend passes IPCBskb2 to...
kernel: ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()
A flaw was found in the Linux kernel's IPv6 ICMP error generation. A remote attacker could send a specially crafted IPv4 ICMP error packet with a Common Internet Protocol Security Option CIPSO IP option. This could lead to incorrect handling of packet control block data when generating an IPv6 IC...

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...
UBUNTU-CVE-2026-46207
In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: fix empty payload in tap skb for non-linear buffers For non-linear skbs, virtiotransportbuildskb goes through virtiotransportcopynonlinearskb to copy the original payload in the new skb to be delivered to the vsockm...
CVE-2026-46207
The CVE-2026-46207 entry describes a Linux kernel fix in vsock/virtio where empty payloads could be copied to the vsockmon tap interface for non-linear skbs due to an uninitialized iov_iter.count in virtio_transport_copy_nonlinear_skb(). The remediation replaces the linear/non-linear split with s...

CVE-2026-46188
In CVE-2026-46188, the Linux kernel octeon_ep_vf path failed to guard the result of napi_build_skb() against NULL on allocation failure, leading to a NULL pointer dereference in __octep_vf_oq_process_rx() for both single-buffer and multi-fragment paths. The fix adds NULL checks after napi_build_s...
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-2026-46123
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...
