SUSE 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 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...
