The vulnerable component fails to properly validate or handle oversized input, leading to out-of-bounds memory access. The attack requires network access to send the large input data to the affected component. A successful exploit can result in denial of service through a crash or, under certain conditions, arbitrary code execution, depending on the memory layout and exploitation technique employed. ## Affected products - Qualcomm ## Timeline - 2026-09-17: disclosed ## References - [https://docs.qualcomm.com/product/publicresources/securitybulletin/september-2026-bulletin.html](https://docs.qualcomm.com/product/publicresources/securitybulletin/september-2026-bulletin.html) ## Related threats - [Qualcomm transient denial of service while parsing frame during channel usage](https://junglewise.ai/threats/cve-2026-25294-qualcomm-transient-denial-of-service-while-parsing-frame-during) - [Qualcomm component memory corruption in buffer validation](https://junglewise.ai/threats/cve-2026-25290-qualcomm-component-memory-corruption-in-buffer-validation) - [Qualcomm component use-after-free information disclosure](https://junglewise.ai/threats/cve-2026-25284-qualcomm-component-use-after-free-information-disclosure) - [Qualcomm buffer overflow in external data handling](https://junglewise.ai/threats/cve-2026-25283-qualcomm-buffer-overflow-in-external-data-handling) - [Qualcomm component out-of-bounds memory access in data processing](https://junglewise.ai/threats/cve-2026-25282-qualcomm-component-out-of-bounds-memory-access-in-data-processing)
