Alpine: multiple valkey packages: security update to 8.1.6-r0

high Tenable Self-Hosted Container Security Plugin ID 439595

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- Valkey is a distributed key-value database. Prior to versions 9.0.2, 8.1.6, 8.0.7, and 7.2.12, a malicious
user can use scripting commands to inject arbitrary information into the response stream for the given
client, potentially corrupting or returning tampered data to other users on the same connection. The error
handling code for lua scripts does not properly handle null characters. Versions 9.0.2, 8.1.6, 8.0.7, and
7.2.12 fix the issue. (CVE-2025-67733)

- Valkey is a distributed key-value database. Prior to versions 9.0.2, 8.1.6, 8.0.7, and 7.2.12, a malicious
actor with access to the Valkey clusterbus port can send an invalid packet that may cause an out bound
read, which might result in the system crashing. The Valkey clusterbus packet processing code does not
validate that a clusterbus ping extension packet is located within buffer of the clusterbus packet before
attempting to read it. Versions 9.0.2, 8.1.6, 8.0.7, and 7.2.12 fix the issue. As an additional
mitigation, don't expose the cluster bus connection directly to end users, and protect the connection with
its own network ACLs. (CVE-2026-21863)

Solution

Update the valkey library and its related packages to version 8.1.6-r0 or later.
