TencentOS Server 2: linux-firmware (TSSA-2023:0274)

medium Nessus Plugin ID 239787

Synopsis

The remote TencentOS Server 2 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0274 advisory.

 Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

 CVE-2023-20569:
 A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled?address, potentially leading to information disclosure.

 CVE-2023-20593:
 An issue in Zen 2 CPUs, under specific microarchitectural circumstances, may allow an attacker to potentially access sensitive information.

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.

Solution

Update the affected packages.
