Severity by source
AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:H
Local unprivileged process feeds bad data across a subsystem boundary (AV:L/PR:L/S:C); OOB read yields limited C:L/I:L and a transient but availability-heavy A:H.

Lifecycle Timeline
3DescriptionCVE.org
Transient DOS when processing unverified data from a neighboring system causes out of bound memory access.
AnalysisAI
Out-of-bounds memory access in Qualcomm Snapdragon platform firmware allows a locally authenticated low-privileged attacker on the device to induce a transient, recoverable denial of service, with minor leakage of confidentiality and integrity. The issue (CWE-125, out-of-bounds read) is triggered when the affected component consumes unvalidated data arriving from a neighboring on-chip subsystem; CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:H gives a vendor score of 7.9, and the scope-change flag reflects impact that crosses from the vulnerable subsystem into other components. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires local access with low privileges (PR:L) on a Qualcomm Snapdragon device and the ability to feed unverified data into the interface that receives input from a neighboring on-chip subsystem; no user interaction is needed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a vendor-scored 7.9 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:H) Qualcomm Snapdragon out-of-bounds read (CWE-125) that manifests as a transient, recoverable denial of service with minor confidentiality/integrity leakage. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch version is identified in the provided data, so the primary action is to consult Qualcomm's September 2026 security bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/september-2026-bulletin.html) to confirm which chipsets are affected, the exact firmware/build that contains the fix, and the OEM distribution timeline, then apply the corresponding OEM firmware update for each affected device model. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all devices using Qualcomm Snapdragon platforms (e.g., smartphones, tablets, laptops, IoT) and confirm whether they are exposed to CVE-2026-25282 by checking vendor advisories; restrict local low-privileged access where feasible. …
