Model 3: Integer Overflow or Wraparound
CVE-2025-2082 is a high-severity integer overflow or wraparound vulnerability in Model 3 from Tesla, with a CVSS 3.0 base score of 7.5 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. Affected Model 3 versions: 2024.8. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.38% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Model 3 Firmware to 2024.14 or a later version.

Official description
Tesla Model 3 VCSEC Integer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected Tesla Model 3 vehicles. Authentication is not required to exploit this vulnerability. The specific flaw exists within the VCSEC module. By manipulating the certificate response sent from the Tire Pressure Monitoring System (TPMS), an attacker can trigger an integer overflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the VCSEC module and send arbitrary messages to the vehicle CAN bus. Was ZDI-CAN-23800.

The underlying weakness: Integer Overflow or Wraparound
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
How developers prevent this class of flaw
- Ensure that all protocols are strictly defined, such that all out-of-bounds behavior can be identified simply, and require strict conformance to the protocol.
- Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. If possible, choose a language or compiler that performs automatic bounds checking.
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. Use libraries or frameworks that make it easier to handle numbers without unexpected consequences. Examples include safe integer handling packages such as SafeInt (C++) or IntegerLib (C or C++).
