Kept AV:N/PR:N because a network-exposed CUPS queue can accept crafted jobs unauthenticated, and code execution in the filter yields full C/I/A impact; AV:N is the worst-case and assumes network printing is enabled.

DescriptionCVE.org

A flaw was found in HPLIP (HP Linux Imaging and Printing Software). This vulnerability, an incomplete fix for CVE-2026-8631, may allow a remote attacker to escalate privileges or achieve arbitrary code execution. This can occur through an integer overflow in the hpcups processing path when handling specially crafted print data.

AnalysisAI

Remote code execution and privilege escalation in HPLIP (HP Linux Imaging and Printing) affects the hpcups print filter across Red Hat Enterprise Linux 6 through 10, where an integer overflow triggered by specially crafted print data can corrupt memory. This is an incomplete-fix follow-up to CVE-2026-8631, meaning the original patch did not fully close the flaw, and no public exploit has been identified at time of analysis. The Red Hat CVSS of 9.8 reflects a network-reachable, unauthenticated attack path, though realistic exploitation depends on how the CUPS print pipeline is exposed.

Technical ContextAI

HPLIP provides the printer drivers and CUPS filters used to drive HP inkjet and laser devices on Linux; the vulnerable component is hpcups, the CUPS raster-to-HP-PCL/PDL filter that converts spooled print jobs into device-specific data. The root cause is CWE-190 (Integer Overflow or Wraparound): while parsing attacker-controlled print/raster data, a size or count value overflows, leading to undersized allocation or out-of-bounds writes and subsequent memory corruption that can be steered toward code execution. Because this is explicitly an incomplete fix for CVE-2026-8631, the same processing path was previously patched but a residual overflow condition remains reachable. The CPE data scopes the affected shipping vehicle to Red Hat Enterprise Linux 6, 7, 8, 9, and 10, all of which package HPLIP for HP printer support.

RemediationAI

No exact fixed HPLIP version is present in the provided data, so treat patch status as: patch tracked per vendor advisory but released fixed version not independently confirmed - monitor https://access.redhat.com/security/cve/CVE-2026-14544 and apply the HPLIP errata update for your RHEL release as soon as it is published, prioritizing this because the prior fix (CVE-2026-8631) was incomplete. As compensating controls until patched, restrict CUPS to local-only operation by ensuring it does not listen on network interfaces or accept shared/remote print jobs (bind cupsd to localhost and disable queue sharing), which removes the network attack path at the cost of losing network printing; alternatively, remove or disable the hpcups filter and use an alternative driver (e.g., driverless IPP Everywhere) for affected HP devices, accepting reduced device-specific feature support; and constrain which hosts can submit jobs via CUPS access controls and firewall rules on the IPP port (631/tcp), which limits exposure but does not protect against a trusted-but-malicious client. Do not rely on the CVE-2026-8631 patch alone, as it does not fully address this flaw.
