CVE-2026-91102
Description
A flaw was found in HP Linux Imaging and Printing (HPLIP) software. Multiple vulnerabilities exist within several software components that could potentially allow an attacker to achieve remote code execution, escalate privileges, cause a denial of service, disclose information, or modify files without authorization under certain conditions.
Mitigation
To reduce the attack surface, restrict network access to systems running HPLIP if network printing or remote management features are not actively used. Alternatively, if HPLIP functionality is not required, the `hplip` package can be removed.
To remove the package:
`sudo dnf remove hplip`
Removing the package will impact printing capabilities 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.
