Detailsinfo

A vulnerability was found in Google Android (Smartphone Operating System) (unknown version). It has been declared as problematic. Affected by this vulnerability is the function probe of the component Linux Kernel. The manipulation with an unknown input leads to a double free vulnerability. The CWE definition for the vulnerability is CWE-415. The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations. As an impact it is known to affect availability. The summary by CVE is:

In all android releases(Android for MSM, Firefox OS for MSM, QRD Android) from CAF using the linux kernel, memory allocated with devm_kzalloc is automatically released by the kernel if the probe function fails with an error code. This may result in data corruption.

The bug was discovered 09/04/2018. The weakness was released 09/18/2018 (Website). It is possible to read the advisory at source.android.com.
