Detailsinfo

A vulnerability was found in Google Android (Smartphone Operating System) (version unknown) and classified as critical. This issue affects the function WLANQCMBR_McProcessMsg of the component Qualcomm. The manipulation of the argument data_len as part of a Variable leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

In all Qualcomm products with Android releases from CAF using the Linux kernel, due to lack of bounds checking on the variable "data_len" from the function WLANQCMBR_McProcessMsg, a buffer overflow may potentially occur in WLANFTM_McProcessMsg.
