Technical details
This is a classic buffer overflow vulnerability in Qualcomm firmware or components that processes external data without proper size validation. When copying data from an untrusted external source, the code fails to verify the input size against the allocated buffer, leading to a heap or stack overflow. The vulnerability requires network or local access to send malformed data to the affected component. Exploitation can result in denial of service (crash) or potentially remote code execution depending on the memory layout and exploitation technique used.
Affected products
- Qualcomm Snapdragon <UNKNOWN>
