前述の説明ブロックは、Tenable が Debian セキュリティアドバイザリから直接抽出したものです。

Nessus はこれらの問題をテストしておらず、代わりにアプリケーションが自己報告するバージョン番号にのみ依存していることに注意してください。

The version of kernel-generic installed on the remote host is prior to 5.15.208 / 5.15.208_smp / 6.12.91 / 6.18.33. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2026-144-01 advisory.

    New kernel packages are available for Slackware 15.0 and -current to fix a security issue.

Tenable has extracted the preceding description block directly from the kernel-generic security advisory.

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

The remote Debian 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6295 advisory.

    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 6.12.90-1. Additionally this update includes a fix for a     regression introduced with MediaTek Bluetooth devices (#1136790).

    We recommend that you upgrade your linux packages.

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.

  - Debian Linux - linux - In the Linux kernel, the following vulnerability has been resolved:  net: skbuff:
    propagate shared-frag marker through frag-transfer helpers  Two frag-transfer helpers     (__pskb_copy_fclone() and skb_shift()) fail to propagate the SKBFL_SHARED_FRAG bit in skb_shinfo()->flags     when moving frags from source to destination.  __pskb_copy_fclone() defers the rest of the shinfo metadata     to skb_copy_header() after copying frag descriptors, but that helper only carries over gso_{size,segs,     type} and never touches skb_shinfo()->flags; skb_shift() moves frag descriptors directly and leaves flags     untouched.  As a result, the destination skb keeps a reference to the same externally-owned or page-cache-     backed pages while reporting skb_has_shared_frag() as false.  The mismatch is harmful in any in-place     writer that uses skb_has_shared_frag() to decide whether shared pages must be detoured through     skb_cow_data().  ESP input is one such writer (esp4.c, esp6.c), and a single nft 'dup to <local>' rule --     or any other nf_dup_ipv4() / xt_TEE caller -- is enough to land a pskb_copy()'d skb in esp_input() with     the marker stripped, letting an unprivileged user write into the page cache of a root-owned read-only file     via authencesn-ESN stray writes.  Set SKBFL_SHARED_FRAG on the destination whenever frag descriptors were     actually moved from the source.  skb_copy() and skb_copy_expand() share skb_copy_header() too but     linearize all paged data into freshly allocated head storage and emerge with nr_frags == 0, so     skb_has_shared_frag() returns false on its own; they need no change.  The same omission exists in     skb_gro_receive() and skb_gro_receive_list(). The former moves the incoming skb's frag descriptors into     the accumulator's last sub-skb via two paths (a direct frag-move loop and the head_frag + memcpy path);
    the latter chains the incoming skb whole onto p's frag_list.  Downstream skb_segment() reads only     skb_shinfo(p)->flags, and skb_segment_list() reuses each sub-skb's shinfo as the nskb -- both p and lp     must carry the marker.  The same omission also exists in tcp_clone_payload(), which builds an MTU probe     skb by moving frag descriptors from skbs on sk_write_queue into a freshly allocated nskb.  The helper     falls into the same family and warrants the same fix for consistency; no TCP TX-side in-place writer is     currently known to reach a user page through this gap, but a future consumer depending on the marker would     regress silently.  The same omission exists in skb_segment(): the per-iteration flag merge takes only     head_skb's flag, and the inner switch that rebinds frag_skb to list_skb on head_skb-frags exhaustion does     not fold the new frag_skb's flag into nskb.  Fold frag_skb's flag at both sites so segments drawing frags     from frag_list members carry the marker.  Red Hat Enterprise Linux - kernel: net: skbuff: propagate     shared-frag marker through frag-transfer helpers (CVE-2026-43503)

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