Note: Versions mentioned in the description apply only to the upstream kernel-devel package and not the kernel-devel package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
