CVE-2026-25290: CWE-190 Integer Overflow or Wraparound in Qualcomm, Inc. Snapdragon
CVE-2026-25290 is an integer overflow or wraparound vulnerability in Qualcomm Snapdragon products WSA8840 and WSA8845. It occurs during validation of large data buffers from external sources when addition is used to check buffer length, potentially leading to memory corruption. The vulnerability has a high severity with a CVSS score of 7.8, impacting confidentiality, integrity, and availability. No patch or remediation information is currently provided by the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
This vulnerability involves an integer overflow or wraparound (CWE-190) in Qualcomm Snapdragon devices WSA8840 and WSA8845. The flaw arises when validating large external data buffers by adding lengths to check buffer boundaries, which can cause memory corruption. The CVSS 3.1 score is 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating a high-impact local attack requiring low privileges and no user interaction. The vendor has not published any patch or mitigation details yet.
Potential Impact
Successful exploitation could lead to memory corruption, resulting in high impact to confidentiality, integrity, and availability of the affected device. This could allow an attacker with local access and low privileges to compromise the system without user interaction. No known exploits are currently reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit local access to trusted users and monitor for unusual behavior related to buffer handling on affected devices.
