CVE-2026-91100
Description
A flaw was found in HP Linux Imaging and Printing (HPLIP) Software. Multiple vulnerabilities in several software components could allow a remote attacker to execute arbitrary code, escalate privileges, or cause a denial of service. Additionally, these flaws could lead to information disclosure or unauthorized file modification under certain conditions.
Mitigation
If HP printer support is not required on the system, remove the HPLIP package to eliminate the attack surface. For Red Hat Enterprise Linux, use `sudo dnf remove hplip`. Removing this package will disable functionality for HP printers.
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.
