Detailsinfo

A vulnerability was found in Qualcomm Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer IoT, Snapdragon IoT, Snapdragon Mobile and Snapdragon Wearables (Chip Software). It has been rated as critical. This issue affects an unknown functionality of the component Array Index Handler. The manipulation with an unknown input leads to a resource consumption vulnerability. Using CWE to declare the problem leads to CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Index of array is processed in a wrong way inside a while loop and result in invalid index (-1 or something else) leads to out of bound memory access. in Snapdragon Auto, Snapdragon Connectivity, Snapdragon Consumer Electronics Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music, Snapdragon Wired Infrastructure and Networking in MDM9206, MDM9607, MDM9640, MDM9650, MSM8996AU, QCA6174A, QCA6574, QCA6574AU, QCA6584, QCA6584AU, QCA9377, QCA9379, QCA9886, SD 210/SD 212/SD 205, SD 425, SD 427, SD 430, SD 435, SD 450, SD 625, SD 820, SD 820A, SD 835, SDX20, SDX24, Snapdragon_High_Med_2016
