High [CVE-2026-64611] cpu exhaustion via infinite loop in cfieee1284normalizemakemodel
CVE-2026-64611Source published Source updated
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. A Moderate denial-of-service vulnerability in libcupsfilters allows network attackers to exhaust CPU resources by sending malformed IEEE-1284 device IDs. Red Hat rates this as Moderate because the vulnerable component, cups-browsed, is disabled by default in RHEL. Red Hat severity: Moderate — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-835. Affected Red Hat products: Red Hat Enterprise Linux 10. Red Hat…
