CVE-2025-32062
Published: 15 February 2026
Summary
CVE-2025-32062 is a high-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Blackhat (inferred from references). Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation of Remote Services (T1210); ranked at the 29.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
CVE-2025-32062 is a stack-based buffer overflow vulnerability (CWE-121) in the Bluetooth stack developed by Alps Alpine within the Infotainment ECU manufactured by Bosch. The flaw arises from insufficient boundary validation of user-supplied data, leading to the overflow when processing a specific packet over an established upper-layer L2CAP channel. It was first identified in the 2020 Nissan Leaf ZE1 model and carries a CVSS v3.1 base score of 8.8 (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
An attacker within adjacent physical proximity—such as Bluetooth range—can exploit this vulnerability with low complexity and no required privileges or user interaction. By sending a crafted packet over the L2CAP channel, the attacker achieves remote code execution on the Infotainment ECU with root privileges, potentially compromising connected vehicle systems.
Advisories and resources, including a Black Hat Asia 2025 presentation on remote exploitation of the Nissan Leaf, a PCA Cybersecurity advisory on vulnerabilities in Bosch-manufactured Nissan infotainment systems, and Nissan's Leaf product page, provide further details on the issue. No specific patch or mitigation guidance is detailed in the available references.
