CVE-2025-32062 — Stack Buffer Overflow leading to RCE in Bluetooth stack of Infotainment ECU

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.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.4% (30-day exploitation probability)+5
Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.
