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 12.9th 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).

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly requires validation of user-supplied data boundaries in Bluetooth L2CAP packets to prevent the stack-based buffer overflow.

SI-16 Memory Protection good match

prevent

Implements memory protections such as stack canaries, ASLR, and DEP to mitigate exploitation of stack-based buffer overflows in the Bluetooth stack even if validation fails.

SI-2 Flaw Remediation good match

prevent

Mandates timely identification, reporting, and correction of the specific buffer overflow flaw in the Alps Alpine Bluetooth stack, eliminating the vulnerability.

MITRE ATT&CK Enterprise TechniquesAI

T1210 Exploitation of Remote Services Lateral Movement

Adversaries may exploit remote services to gain unauthorized access to internal systems once inside of a network.

T1068 Exploitation for Privilege Escalation Privilege Escalation

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.

Why these techniques?

Buffer overflow in Bluetooth L2CAP stack directly enables remote exploitation of a service for unauthenticated RCE and root privilege escalation from adjacent range.

NVD Description

The specific flaw exists within the Bluetooth stack developed by Alps Alpine of the Infotainment ECU manufactured by Bosch. The issue results from the lack of proper boundary validation of user-supplied data, which can result in a stack-based buffer overflow…

when receiving a specific packet on the established upper layer L2CAP channel. An attacker can leverage this vulnerability to obtain remote code execution on the Infotainment ECU with root privileges. First identified on Nissan Leaf ZE1 manufactured in 2020.

Deeper analysisAI

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.
