CVE-2026-25283: CWE-121 Stack-based Buffer Overflow in Qualcomm, Inc. Snapdragon
CVE-2026-25283 is a high severity stack-based buffer overflow vulnerability in Qualcomm Snapdragon devices WSA8840 and WSA8845. It occurs due to memory corruption when copying unverified data from an external source that exceeds the allocated buffer size. This vulnerability can lead to complete compromise of confidentiality, integrity, and availability.
AI Analysis
Technical Summary
This vulnerability (CWE-121) involves a stack-based buffer overflow in Qualcomm Snapdragon products WSA8840 and WSA8845. The flaw arises when unverified external data is copied into a buffer without proper bounds checking, causing memory corruption. The CVSS 3.1 score is 8.8 (high), with attack vector local, low attack complexity, low privileges required, no user interaction, and scope changed. The impact includes high confidentiality, integrity, and availability loss. No vendor patch or advisory is provided in the data, and no known exploits are reported in the wild.
Potential Impact
Successful exploitation can result in memory corruption leading to potential arbitrary code execution or system compromise, affecting confidentiality, integrity, and availability of the affected Snapdragon devices.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit local access to affected devices and monitor for unusual behavior.
