"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by a vulnerability as referenced in the
ALINUX3-HOTFIX-SA-2026:0001 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2026-43284:
    In the Linux kernel, the following vulnerability has been resolved:
    xfrm: esp: avoid in-place decrypt on shared skb frags
    MSG_SPLICE_PAGES can attach pages from a pipe directly to an skb. TCP
    marks such skbs with SKBFL_SHARED_FRAG after skb_splice_from_iter(),
    so later paths that may modify packet data can first make a private
    copy. The IPv4/IPv6 datagram append paths did not set this flag when
    splicing pages into UDP skbs.
    That leaves an ESP-in-UDP packet made from shared pipe pages looking
    like an ordinary uncloned nonlinear skb. ESP input then takes the no-COW
    fast path for uncloned skbs without a frag_list and decrypts in place
    over data that is not owned privately by the skb.
    Mark IPv4/IPv6 datagram splice frags with SKBFL_SHARED_FRAG, matching
    TCP. Also make ESP input fall back to skb_cow_data() when the flag is
    present, so ESP does not decrypt externally backed frags in place.
    Private nonlinear skb frags still use the existing fast path.
    This intentionally does not change ESP output. In esp_output_head(),
    the path that appends the ESP trailer to existing skb tailroom without
    calling skb_cow_data() is not reachable for nonlinear skbs:
    skb_tailroom() returns zero when skb->data_len is nonzero, while ESP
    tailen is positive. Thus ESP output will either use the separate
    destination-frag path or fall back to skb_cow_data().

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
