Summary

Details

OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. Prior to 2.4.17, a network-adjacent attacker can send a crafted SNMP response to the CUPS SNMP backend that causes an out-of-bounds read of up to 176 bytes past a stack buffer. The leaked memory is converted from UTF-16 to UTF-8 and stored as printer supply description strings, which are subsequently visible to authenticated users via IPP Get-Printer-Attributes responses and the CUPS web interface. This vulnerability is fixed in 2.4.17.

Details

Ariel Silver discovered that CUPS incorrectly handled username comparisons during authorization checks. A local attacker could possibly use this issue to gain unauthorized access to restricted operations. (CVE-2026-27447)

Asim Viladi Oglu Manizada discovered that CUPS incorrectly handled notify-recipient-uri values in the RSS notifier. A remote attacker could possibly use this issue to overwrite lp-writable files and cause a denial of service. (CVE-2026-34978)

Jacob Newman discovered that CUPS incorrectly handled filter option strings when processing job attributes. An attacker could use this issue to cause CUPS to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2026-34979)

Asim Viladi Oglu Manizada discovered that CUPS incorrectly handled page-border values in shared PostScript queues. A remote attacker could possibly use this issue to execute arbitrary code. (CVE-2026-34980)

Asim Viladi Oglu Manizada discovered that CUPS incorrectly handled localhost authentication to attacker-controlled IPP services. A local attacker could possibly use this issue to overwrite arbitrary files and execute arbitrary code. (CVE-2026-34990)

Tomer Fichman discovered that CUPS incorrectly handled negative job-password-supported values. A local attacker could possibly use this issue to cause CUPS to crash, resulting in a denial of service. (CVE-2026-39314)

Tomer Fichman discovered that CUPS incorrectly handled temporary printer deletion. An attacker could possibly use this issue to cause CUPS to crash, resulting in a denial of service, or to execute arbitrary code. (CVE-2026-39316)

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.
