The vulnerability stems from a cryptographic issue where a lack of proper authentication allows for unauthorized modification of the boot flow. This could potentially allow an attacker with local access to modify the system\u0026rsquo;s boot process, leading to arbitrary code execution or other malicious activities. This vulnerability was disclosed in Qualcomm\u0026rsquo;s June 2026 security bulletin. The impact of this vulnerability could be significant, as it could allow attackers to bypass security measures and gain unauthorized access to sensitive data or system functionalities.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker gains local access to a device with a vulnerable Qualcomm chipset.\u003c/li\u003e\n\u003cli\u003eAttacker analyzes the partition table structure and identifies the cryptographic flaw.\u003c/li\u003e\n\u003cli\u003eAttacker crafts a malicious partition table entry, exploiting the missing authentication (CWE-306).\u003c/li\u003e\n\u003cli\u003eAttacker modifies the partition table using specialized tools or scripts, injecting the malicious entry.\u003c/li\u003e\n\u003cli\u003eThe device is rebooted, and the bootloader processes the modified partition table.\u003c/li\u003e\n\u003cli\u003eDue to the cryptographic vulnerability, the malicious partition table entry is processed without proper validation.\u003c/li\u003e\n\u003cli\u003eThe boot flow is altered, potentially redirecting execution to attacker-controlled code.\u003c/li\u003e\n\u003cli\u003eAttacker gains control of the device\u0026rsquo;s boot process, leading to arbitrary code execution and potential system compromise.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-24090 allows an attacker to modify the device\u0026rsquo;s boot flow, potentially leading to complete device compromise. Given the widespread use of Qualcomm chipsets in mobile devices, embedded systems, and IoT devices, a large number of devices could be vulnerable. The unauthorized modification of the boot flow can lead to data theft, installation of malware, or even bricking the device.
