In an ioctl handler in all Qualcomm products with Android for MSM, Firefox OS for MSM, or QRD Android, several sanity checks are missing which can lead to out-of-bounds accesses.

When a control related to codec is issued from userspace in all Qualcomm products with Android for MSM, Firefox OS for MSM, or QRD Android, the type casting is done to the container structure instead of the codec's individual structure, resulting in a device restart after kernel crash occurs.

In a display driver in all Qualcomm products with Android for MSM, Firefox OS for MSM, or QRD Android, a variable controlled by userspace is used to calculate offsets and sizes for copy operations, which could result in heap overflow.

In an audio driver in all Qualcomm products with Android for MSM, Firefox OS for MSM, or QRD Android, if a function is called with a very large length, an integer overflow could occur followed by a heap buffer overflow.

In a sound driver in all Qualcomm products with Android for MSM, Firefox OS for MSM, or QRD Android, if a function is called with a very large length, an integer overflow could occur followed by a buffer overflow.

In an ioctl handler in all Qualcomm products with Android for MSM, Firefox OS for MSM, or QRD Android, if a user supplies a value too large, then an out-of-bounds read occurs.

In a driver in all Qualcomm products with Android for MSM, Firefox OS for MSM, or QRD Android, a user-supplied buffer is casted to a structure without checking if the source buffer is large enough.

In a driver in all Qualcomm products with Android for MSM, Firefox OS for MSM, or QRD Android, kernel heap memory can be exposed to userspace.

In an audio driver in all Qualcomm products with Android releases from CAF using the Linux kernel, when a sanity check encounters a length value not in the correct range, an error message is printed, but code execution continues in the same way as for a correct length value.

In all Qualcomm products with Android releases from CAF using the Linux kernel, kernel stack data can be leaked to userspace by an audio driver.

The updateMessageStatus function in Android 5.1.1 and earlier allows local users to cause a denial of service (NULL pointer exception and process crash).

In Lenovo Connect2 versions earlier than 4.2.5.4885 for Windows and 4.2.5.3071 for Android, when an ad-hoc connection is made between two systems for the purpose of sharing files, the password for this ad-hoc connection will be stored in a user-readable location. An attacker with read access to the user's contents could connect to the Connect2 hotspot and see the contents of files while they are being transferred between the two systems.

An elevation of privilege vulnerability in the NVIDIA sound driver could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process. Product: Android. Versions: N/A. Android ID: A-34373711. References: N-CVE-2017-6249.
