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...

UBUNTU-CVE-2026-46234

In the Linux kernel, the following vulnerability has been resolved: vsock: fix buffer size clamping order In vsockupdatebuffersize, the buffer size was being clamped to the maximum first, and then to the minimum. If a user sets a minimum buffer size larger than the maximum, the minimum check...

CVE-2026-46234

CVE-2026-46234 affects the Linux kernel vsock code, specifically the vsock_update_buffer_size path. The bug arises from clamping the buffer size: it first enforces the maximum, then the minimum, which allows vsk->buffer_size to exceed vsk->buffer_max_size when a larger minimum is configured...

CVE-2026-46214

CVE-2026-46214 relates to the Linux kernel vsock/virtio transport: a backlog count leak occurs when vsock_assign_transport() fails or switches transport, because sk_acceptq_added() is called before transport validation and not removed on error. This can cause sk_acceptq_is_full() to reject new co...

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...
