In the function wmi_set_ie(), the length validation code does not handle unsigned integer overflow properly. As a result, a large value of the 'ie_len' argument can cause a buffer overflow in all Android releases from CAF (Android for MSM, Firefox OS for MSM, QRD Android) using the Linux Kernel.
In the function wmi_set_ie() in the Linux kernel the length validation code does not handle unsigned integer overflow properly. As a result, a large value of the ‘ie_len’ argument can cause a buffer overflow and thus a memory corruption leading to a system crash or other or unspecified impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.
