CVE-2024-52337: Tuned: improper sanitization of `instance_name` parameter of the `instance_create()` method

A log spoofing flaw was found in the Tuned package due to improper sanitization of some API arguments. This flaw allows an attacker to pass a controlled sequence of characters; newlines can be inserted into the log. Instead of the 'evil' the attacker could mimic a valid TuneD log line and trick the administrator. The quotes '' are usually used in TuneD logs citing raw user input, so there will always be the ' character ending the spoofed input, and the administrator can easily overlook this. This logged string is later used in logging and in the output of utilities, for example, `tuned-adm get_instances` or other third-party programs that use Tuned's D-Bus interface for such operations.

Security readout for executives and security teams

Plain-English summary

CVE-2024-52337 lets a local, low-privileged user manipulate TuneD log entries by injecting newline characters into an instance name. The main risk is misleading administrators or tools that rely on TuneD logs or instance output. It is not described as remote code execution or data theft.

Executive priority

Handle in normal patch cycles unless TuneD logs drive compliance, monitoring, or automated operations. Prioritize shared multi-user Linux systems and administrative jump hosts where local users could mislead operators or incident responders.

Technical view

TuneD improperly sanitizes the instance_name parameter in the instance_create() API method. Controlled characters can be written into logs and later shown by utilities such as tuned-adm get_instances or programs using the TuneD D-Bus interface. CVSS 3.1 is 5.5: local attack vector, low complexity, low privileges, no user interaction, high integrity impact.

Likely exposure

Exposure is mainly Linux systems running affected tuned packages, especially listed Red Hat Enterprise Linux, Fast Datapath, EUS, ELS, SAP, NFV, and real-time streams. Exploitation requires local access and low privileges, so internet-facing exposure is not the primary concern.

Exploitation context

The source bundle does not show CISA KEV listing or cited active exploitation. The realistic impact is log and output spoofing that can confuse investigations, monitoring, or administrator decisions. This may matter more on systems where TuneD logs feed automation or security review workflows.

Researcher notes

This is CWE-20 input validation failure with integrity impact through log spoofing, not direct privilege escalation. Key review areas are TuneD D-Bus callers, consumers of tuned-adm get_instances, and any tooling that parses TuneD logs as authoritative records.

Mitigation direction

  • Apply the relevant Red Hat security advisory updates for your subscribed product stream.
  • For non-Red Hat builds, check TuneD upstream and distribution guidance before upgrading.
  • Restrict TuneD D-Bus/API access to trusted local users where operationally feasible.
  • Treat TuneD logs and instance output as potentially untrusted until patched.

Validation and detection

  • Inventory systems with the tuned package installed.
  • Compare installed package versions against Red Hat CVE and errata applicability.
  • Confirm the relevant RHSA update is installed for each product stream.
  • Review TuneD-related logs for suspicious multiline or malformed entries.
