Physical hardware/USB path to the HPLIP stack sets AV:P; no auth or interaction needed (PR:N/UI:N); integer underflow yields only a crash so C:N/I:N/A:H.

Lifecycle Timeline
4DescriptionCVE.org
HP has identified and remediated multiple externally reported vulnerabilities within HPLIP. The findings affect several software components that could potentially enable remote code execution, privilege escalation, denial of service, information disclosure, or unauthorized file modification under certain conditions.
AnalysisAI
Denial of service in HP's HPLIP (HP Linux Imaging and Printing Software) printing stack is reachable when a physically-present attacker supplies specially crafted input that triggers a CWE-191 integer underflow, crashing or hanging affected components; the scored CVSS:3.1 vector (AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) limits impact to availability only, with no confidentiality or integrity loss. The physical attack vector (direct hardware/USB or local physical access) is the dominant gating factor and rules out remote or network-based exploitation, and no public exploit has been identified at time of analysis. …

Vulnerability AssessmentAI
| Exploitation | Requires physical attack vector (AV:P): the attacker must have local physical access or a direct hardware/USB connection to a system running HP's HPLIP printing stack to supply the input that triggers the CWE-191 integer underflow. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but low-priority issue. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | HP has stated that the reported HPLIP issues were identified and remediated, so patch status is 'Patch available per vendor advisory' - consult HP Security Bulletin hpsbpi04151 (https://support.hp.com/us-en/document/ish_15646959-15646984-16/hpsbpi04151) for the exact fixed HPLIP release applicable to your distribution, then upgrade HPLIP to that version or install the vendor-repackaged update from your Linux distribution rather than building from unpatched sources. … Detailed patch versions, workarounds, and compensating controls in full report. |
