CVE-2026-14544: Integer Overflow or Wraparound in Red Hat Red Hat Enterprise Linux 10
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.
AI Analysis
Technical Summary
This vulnerability involves an integer overflow or wraparound in the hpcups processing path of HPLIP, which is used for HP printer drivers on Red Hat Enterprise Linux 10. The flaw is a result of an incomplete fix for CVE-2026-8631. Exploitation could lead to privilege escalation or arbitrary code execution without requiring user interaction or privileges. Red Hat has issued important security advisories (RHSA-2026:39976 for RHEL 10 and RHSA-2026:40831 for RHEL 9) providing updated HPLIP packages that address this vulnerability. The advisories cover multiple architectures including x86_64, s390x, ppc64le, and aarch64. Detailed update instructions are available from Red Hat's official articles.
Potential Impact
Successful exploitation of this vulnerability could allow a remote attacker to escalate privileges or execute arbitrary code on affected systems. The CVSS v3.1 base score is 9.8 (critical), reflecting the potential for complete system compromise with no required privileges or user interaction. This poses a significant risk to the confidentiality, integrity, and availability of affected systems running vulnerable versions of HPLIP on Red Hat Enterprise Linux 10 and 9.
Mitigation Recommendations
Red Hat has released updated HPLIP packages that fix this vulnerability. Users should apply the security updates provided in advisories RHSA-2026:39976 (for RHEL 10) and RHSA-2026:40831 (for RHEL 9) as soon as possible. The advisories include detailed instructions and package versions to update. Patch status is official-fix. No additional mitigations are indicated by the vendor advisory.
