CVE-2026-3560: CWE-122: Heap-based Buffer Overflow in Philips Hue Bridge
CVE-2026-3560 is a heap-based buffer overflow vulnerability in the Philips Hue Bridge's HomeKit implementation, specifically in the hk_hap_pair_storage_put function. This flaw allows network-adjacent attackers to execute arbitrary code without authentication by sending specially crafted data to TCP port 8080. The vulnerability arises from improper validation of user-supplied data length before copying it to a heap buffer. It affects version 1.73.1973146020 of the Philips Hue Bridge. The CVSS score is 8.8, indicating high severity. No patch or official remediation guidance is currently provided by the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
The Philips Hue Bridge version 1.73.1973146020 contains a heap-based buffer overflow vulnerability (CWE-122) in the HomeKit hk_hap_pair_storage_put function, which listens on TCP port 8080. The vulnerability is due to insufficient validation of the length of user-supplied data before copying it to a heap buffer, enabling remote code execution by network-adjacent attackers without requiring authentication. This vulnerability was assigned CVE-2026-3560 and has a CVSS v3.0 score of 8.8 (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). The flaw was reported by ZDI as ZDI-CAN-28469. No patch or vendor advisory is currently available.
Potential Impact
Successful exploitation allows an unauthenticated, network-adjacent attacker to execute arbitrary code on the Philips Hue Bridge device, potentially leading to full compromise of the device. This impacts confidentiality, integrity, and availability of the affected system. Given the device's role in smart home environments, compromise could affect connected lighting and related automation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, limit network exposure of the Philips Hue Bridge, especially restricting access to TCP port 8080 from untrusted networks. Monitor for vendor updates and apply patches promptly once available.
