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-2026:1435 advisory.

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

    CVE-2026-80212:
    An issue was discovered in the resolv gem before 0.7.2 for Ruby. Resolv::DNS::Resource.get_class,     Resolv::DNS::Resource::Generic.create, and Resolv::DNS::SvcParam::Generic.create generate a new class for     each unknown DNS resource record (type, class) pair, or each unknown SvcParamKey, encountered while     decoding a response. Each generated class was permanently registered both as a constant on Resource (or     SvcParam::Generic) and as an entry in a class-lookup hash (ClassHash), and thus the class remained     reachable through that constant after the response was discarded. Type and class are each 16-bit values,     and thus an attacker controlling DNS responses (a spoofed response, or a malicious or hijacked upstream     DNS server) has roughly 2^32 distinct (type, class) pairs to choose from. A single response of a few     hundred kilobytes carrying tens of thousands of distinct unknown types permanently grows process memory by     tens of megabytes; repeated responses accumulate without bound and are never reclaimed by garbage     collection, because the constant keeps each class alive. Any code path that calls     Resolv::DNS::Message.decode on attacker-influenced DNS responses is affected. resolv is a default gem, and     thus this is reachable from a plain Ruby installation without any additional dependency.

    CVE-2026-88030:
    Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB     Ruby Driver can cause a caller-supplied structured file identifier to be interpreted as a query condition     rather than as a literal identifier. An authenticated user who can influence the identifier passed by an     affected application may obtain stored file content beyond the intended target or cause all GridFS file     chunks in the affected bucket to be removed, rendering stored file content unreadable.

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

  - Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB     Ruby Driver can cause a caller-supplied structured file identifier to be interpreted as a query condition     rather than as a literal identifier.
