CVE-2026-15203 Aug 26, 05:36 CRITICAL PATCH Act Now

Improper access control on the debug and engineering interfaces of Danfoss iC7-Automation SP, iC7-Marine, and iC7-Hybrid GR3 drive platforms lets attackers read and write internal device values and, more critically, upload and execute unsigned applications, EEPROM data, and firmware through exposed service and software-update mechanisms. Rated CVSS 4.0 9.3, the flaw effectively bypasses code-signing and grants full control over affected industrial drive controllers. There is no public exploit identified at time of analysis, but the missing authentication and firmware-overwrite capability make this a severe integrity and availability risk for operational technology environments.

CVE-2026-8989 Jul 21, 21:24 HIGH POC This Week

Physical firmware compromise in Autel MaxiCharger Single EV charging stations (firmware through V1.03.51) lets an attacker with hands-on access exploit exposed NXP i.MX6 hardware recovery pins to boot unsigned, attacker-controlled code into memory. Once in recovery mode the attacker can dump, modify, or replace the device firmware and extract sensitive data such as credentials, keys, or configuration. Publicly available exploit code exists (published by CyberDanube), though there is no public exploit identified as being used in active campaigns and the flaw is not listed in CISA KEV.

CVE-2026-8988 Jul 21, 21:21 HIGH POC This Week

Physical compromise of Autel MaxiCharger Single EV charging stations running firmware through V1.03.51 is possible via an unprotected UART interface that lets an attacker halt boot and drop into the U-Boot bootloader. From the bootloader an attacker can rewrite boot configuration or the filesystem to gain full operating-system access on the charger. Publicly available exploit code exists (published by CyberDanube), though there is no public exploit identified as being used in active attacks and the flaw requires physical access.

CVE-2024-36319 Feb 12, 18:16 Monitor

Debug code left active in AMD's Video Decoder Engine Firmware (VCN FW) could allow a attacker to submit a maliciously crafted command causing the VCN FW to perform read/writes HW registers, potentially impacting confidentiality, integrity and availabilability of the system.

CVE-2025-15083 Dec 25, 18:15 LOW POC Monitor

UART interface debug and test access control bypass in TOZED ZLT M30s firmware versions up to 1.47 allows physical attackers to access on-chip debug interfaces with improper authentication, leading to information disclosure and potential system manipulation. Exploitation requires direct physical device access and is difficult to execute, but publicly available exploit code exists and the vendor has not responded to disclosure. With an EPSS score of 0.03% and CVSS 0.3, real-world risk is minimal despite public POC availability.
