Background

The Hewlett-Packard Linux Imaging and Printing (HPLIP) project provides essential drivers for HP printers and multi-function devices on Linux systems. It enables users to print, scan, and manage their HP devices seamlessly. However, recent vulnerabilities have been identified that could compromise system security, allowing unauthorized access and execution of arbitrary code.

Vulnerability Detail

The vulnerabilities in HPLIP stem from improper handling of user inputs, leading to privilege escalation and arbitrary code execution. Specifically, CVE-2026-8632 allows attackers to inject operating system commands, while CVE-2026-8631 results from an integer overflow in the hpcups component, both of which can be exploited to gain elevated privileges and execute malicious code on affected systems.

How To Fix

Minimum fixed version

3.18.4-13.el8_10.alma.1

This is the first release that contains the fix.

Workaround

As a temporary measure, users can restrict access to the HPLIP services or disable the affected components until the update is applied. However, this is not a permanent solution and should be followed by an update as soon as possible.

Conclusion

The identified vulnerabilities in HPLIP pose significant risks to system security, allowing for privilege escalation and arbitrary code execution. It is crucial for users to update their HPLIP packages to the latest version to mitigate these risks effectively.
