The flaw arises from a buffer copy operation that fails due to an integer overflow. This overflow occurs during the process of calculating the buffer size required for the attestation report, potentially leading to a write beyond the allocated buffer. Successful exploitation could allow an attacker to overwrite adjacent memory regions, potentially leading to arbitrary code execution or a denial-of-service condition. The vulnerability has a CVSS v3.1 base score of 7.8, indicating a high severity. The vulnerability was reported by Qualcomm and affects Qualcomm products that use attestation report generation. Defenders should monitor for unexpected memory access violations related to attestation services.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker crafts input to trigger attestation report generation.\u003c/li\u003e\n\u003cli\u003eThe system initiates an attestation report generation process.\u003c/li\u003e\n\u003cli\u003eAn integer overflow occurs during the buffer size calculation for the report.\u003c/li\u003e\n\u003cli\u003eA buffer is allocated based on the incorrect, smaller size resulting from the overflow.\u003c/li\u003e\n\u003cli\u003eData is copied into the undersized buffer during the attestation report creation.\u003c/li\u003e\n\u003cli\u003eThe buffer copy operation overwrites memory beyond the allocated buffer\u0026rsquo;s boundaries.\u003c/li\u003e\n\u003cli\u003eCorrupted memory leads to a crash or potentially allows for arbitrary code execution.\u003c/li\u003e\n\u003cli\u003eAttacker gains control of the system or causes a denial-of-service.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2025-47389 can lead to memory corruption, potentially enabling arbitrary code execution.
