Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2025-65396

Severity Medium
Score 6.1/10

Summary

A vulnerability in the boot process of Blurams Flare Camera version 24.1114.151.929 and earlier allows a physically proximate attacker to hijack the boot mechanism and gain a bootloader shell via the UART interface. This is achieved by inducing a read error from the SPI flash memory during the boot, by shorting a data pin of the IC to ground. An attacker can then dump the entire firmware, leading to the disclosure of sensitive information including cryptographic keys and user configurations.

CWE-119 - Buffer Overflow

Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
