Detailsinfo

A vulnerability was found in Qualcomm Snapdragon Auto, Snapdragon Consumer Electronics Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice and Music (Chip Software). It has been declared as critical. This vulnerability affects an unknown function of the component FW Response Handler. The manipulation with an unknown input leads to a integer overflow vulnerability. The CWE definition for the vulnerability is CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Improper validation of event buffer extracted from FW response can lead to integer overflow, which will allow to pass the length check and eventually will lead to buffer overwrite when event data is copied to context buffer in Snapdragon Auto, Snapdragon Consumer Electronics Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music in MDM9607, Nicobar, QCA6574AU, QCN7605, QCS405, QCS605, SDM660, SDM845, SDX55, SM6150, SM7150, SM8150, SM8250, SXR1130, SXR2130
