CVE-2026-64611 (GCVE-0-2026-64611)

Vulnerability from cvelistv5 – Published: 2026-07-23 10:46 – Updated: 2026-08-19 13:34

Title

Libcupsfilters: cups-filters: libcupsfilters: cpu exhaustion via infinite loop in cfieee1284normalizemakemodel()

Summary

A flaw was found in libcupsfilters. The cfIEEE1284NormalizeMakeModel() function enters an infinite loop when processing a printer-advertised IEEE-1284 device ID with an empty model field, causing sustained CPU consumption. A network-adjacent attacker could exploit this by broadcasting a specially crafted printer advertisement, leading to denial of service.

Severity

CVE-2026-64612 (GCVE-0-2026-64612)

Vulnerability from cvelistv5 – Published: 2026-07-20 17:33 – Updated: 2026-08-24 09:42

Title

Libcupsfilters: cups-filters: libcupsfilters: cups image filter process abort via malformed png

Summary

A flaw was found in libcupsfilters and cups-filters. The PNG image reading function creates a libpng reader without installing an error recovery handler, causing the CUPS image filter process to abort when processing a malformed PNG file. An unauthenticated attacker could exploit this by submitting a specially crafted PNG print job, leading to denial of service of the in-flight print job.

Severity

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
