Lifecycle Timeline
3DescriptionCVE.org
Transient DOS when processing large or numerous request buffers without sufficient memory allocation validation.
AnalysisAI
Denial of service in Qualcomm Snapdragon-based devices allows adjacent-network attackers to cause a transient, recoverable outage by sending large or numerous request buffers to a subsystem that fails to validate memory allocation. The vulnerability requires no authentication or user interaction but demands proximity within radio/link-layer range (CVSS 3.1 score 7.4, AV:A/PR:N/UI:N). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires adjacent-network access (AV:A) - the attacker must be within radio/link-layer range of a Snapdragon-based device, not on the open internet. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but bounded-severity issue. … 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 | Vendor-released patches are available per Qualcomm's September 2026 security bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/september-2026-bulletin.html); apply the firmware updates for all affected Snapdragon chipsets as specified in that advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all Qualcomm Snapdragon-based devices in your environment and determine which are exposed to adjacent-network attackers; within 7 days, implement network segmentation to limit radio/link-layer access and monitor for abnormal request buffers that could trigger outages; within 30 days, develop a patching plan to deploy vendor fixes once released, and review physical security for critical devices to reduce proximity risks.
