"The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:1141 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2026-56846:
    A flaw in Node.js HTTP/2 handling can cause HTTP/2 retained header blocks evade maxSessionMemory and
    enable remote memory exhaustion.

    This vulnerability affects Node.js **24.x** and **22.x**.

    CVE-2026-56848:
    A flaw in Node.js HTTP/2 handling allows nghttp2_session_mem_send() to be called re-entrantly while
    nghttp2_session_mem_recv() is executing, resulting in a heap-use-after-free.

    This vulnerability affects Node.js **26.x**, **24.x**, and **22.x**.

    CVE-2026-58043:
    A flaw in Node.js Permission Model enforcement can over-grant filesystem access across radix-tree prefix
    boundaries.

    Under --permission, an attacker who is granted access to one path can abuse boundary handling to read from
    or write to paths outside the intended filesystem allowlist.

    This vulnerability affects Node.js **main**, **22.x**, **24.x**, and **26.x**.

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

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