CVE-2026-91103

Description

A flaw was found in HPLIP (HP Linux Imaging and Printing) software. This issue encompasses multiple vulnerabilities across several components, potentially allowing an attacker to achieve remote code execution, elevate their privileges, or cause a denial of service. Additionally, these flaws could lead to information disclosure or unauthorized file modification under certain conditions.

Mitigation

HPLIP is a collection of drivers for HP printers. If HP printers are not in use, the `hplip` package can be removed to eliminate the attack surface.

To remove the package:
`sudo dnf remove hplip`

This action may affect printing functionality for HP devices.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.
