In the Linux kernel, the following vulnerability has been resolved: net: tap: set skb->dev before parsing virtio net header in tap_get_user_xdp() The commit 4f61f133f354 ("net: tap: NULL pointer derefence in dev_parse_header_protocol when skb->dev is null") fixed a crash in tap_get_user() by assigning skb->dev before calling tun_vnet_hdr_to_skb(). This is required because virtio_net_hdr_to_skb() may invoke dev_parse_header_protocol(), which dereferences skb->dev. Without the assignment, a NULL pointer dereference can occur. However, tap_get_user_xdp() still parses the virtio-net header before assigning skb->dev. When the vhost TX path passes an XDP buffer containing a GSO virtio-net header but the protocol is set to zero on purpose, tun_vnet_hdr_to_skb() can reach dev_parse_header_protocol() while skb->dev is still NULL, resulting in a crash. Fix this by looking up the tap device and assigning skb->dev before calling tun_vnet_hdr_to_skb(), matching the ordering already used in tap_get_user(). Preserve the existing RCU read-side critical section across dev_queue_xmit().

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.105-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:
    https://security-tracker.debian.org/tracker/linux

    Further information about Debian Security Advisories, how to apply     these updates to your system and frequently asked questions can be     found at: https://www.debian.org/security/

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - net: tap: set skb->dev before parsing virtio net header in tap_get_user_xdp() The commit 4f61f133f354     (net: tap: NULL pointer derefence in dev_parse_header_protocol when skb->dev is null) fixed a crash in     tap_get_user() by assigning skb->dev before calling tun_vnet_hdr_to_skb(). This is required because     virtio_net_hdr_to_skb() may invoke dev_parse_header_protocol(), which dereferences skb->dev. Without the     assignment, a NULL pointer dereference can occur. However, tap_get_user_xdp() still parses the virtio-net     header before assigning skb->dev. When the vhost TX path passes an XDP buffer containing a GSO virtio-net     header but the protocol is set to zero on purpose, tun_vnet_hdr_to_skb() can reach     dev_parse_header_protocol() while skb->dev is still NULL, resulting in a crash. Fix this by looking up the     tap device and assigning skb->dev before calling tun_vnet_hdr_to_skb(), matching the ordering already used     in tap_get_user(). Preserve the existing RCU read-side critical section across dev_queue_xmit().
    (CVE-2026-74684)

Note that Nessus relies on the presence of the package as reported by the vendor.
