The vulnerability stems from improper handling of malformed input during the processing of fastboot commands. Successful exploitation of this issue could allow an attacker with physical access to corrupt memory, potentially leading to code execution within the fastboot environment. This vulnerability was disclosed in Qualcomm\u0026rsquo;s June 2026 Security Bulletin. This issue poses a risk to device integrity and confidentiality, particularly in environments where unauthorized physical access to devices is possible.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker gains physical access to a vulnerable Qualcomm device.\u003c/li\u003e\n\u003cli\u003eAttacker places the device into fastboot mode (e.g., by holding specific button combinations during boot).\u003c/li\u003e\n\u003cli\u003eAttacker connects the device to a host machine via USB.\u003c/li\u003e\n\u003cli\u003eAttacker uses the fastboot tool to send a crafted, improperly formatted command to the device.
