This vulnerability occurs when one driver makes an Input/Output Control (IOCTL) call to another driver using a malformed or invalid input/output buffer. The flaw stems from improper validation or handling of the provided buffer, leading to a memory corruption condition. Successful exploitation of this vulnerability could lead to arbitrary code execution, privilege escalation, or a denial-of-service condition. This vulnerability was disclosed in the May 2026 Qualcomm Security Bulletin. The potential impact necessitates that detection engineering teams prioritize identifying and mitigating this threat across systems utilizing affected Qualcomm components.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn attacker gains initial access to the system, potentially through social engineering or exploiting another vulnerability.\u003c/li\u003e\n\u003cli\u003eThe attacker identifies a vulnerable Qualcomm driver that is susceptible to IOCTL calls with invalid buffers.\u003c/li\u003e\n\u003cli\u003eThe attacker develops a malicious driver or application capable of making IOCTL calls.\u003c/li\u003e\n\u003cli\u003eThe malicious driver crafts a specific IOCTL request with a purposefully malformed input/output buffer.\u003c/li\u003e\n\u003cli\u003eThe malicious driver sends the crafted IOCTL request to the targeted Qualcomm driver.\u003c/li\u003e\n\u003cli\u003eThe targeted Qualcomm driver receives the IOCTL request and attempts to process the invalid buffer.\u003c/li\u003e\n\u003cli\u003eDue to the malformed buffer, the driver\u0026rsquo;s memory management routines are corrupted, leading to a write to an arbitrary memory location.\u003c/li\u003e\n\u003cli\u003eThe attacker leverages the memory corruption to execute arbitrary code, escalate privileges, or cause a denial-of-service condition.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2025-47408 can have severe consequences.
