Summary

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

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Forced Integer Overflow
    This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.
