Synopsis
The remote TencentOS Server 3 host is missing one or more security updates.Description
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**.
