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

Vulnerability from cvelistv5 – Published: 2026-07-23 10:46 – Updated: 2026-07-23 20:15

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

7.5 (High)
