A information disclosure vulnerability in the N/A memory subsystem. Product: Android. Versions: Android kernel. Android ID: A-35764946.

In all Qualcomm products with Android releases from CAF using the Linux kernel, a race condition in a WLAN driver can lead to a Use After Free condition.

In all Qualcomm products with Android releases from CAF using the Linux kernel, a race condition in a USB driver can lead to a Use After Free condition.

In all Qualcomm products with Android releases from CAF using the Linux kernel, a race condition in two KGSL driver functions can lead to a Use After Free condition.

In all Qualcomm products with Android releases from CAF using the Linux kernel, if a pointer argument coming from userspace is invalid, a driver may use an uninitialized structure to log an error message.

In all Qualcomm products with Android releases from CAF using the Linux kernel, if a userspace string is not NULL-terminated, kernel memory contents can leak to system logs.

In all Qualcomm products with Android releases from CAF using the Linux kernel, in a video driver, memory corruption can potentially occur due to lack of bounds checking in a memcpy().

In all Qualcomm products with Android releases from CAF using the Linux kernel, in function __mdss_fb_copy_destscaler_data(), variable ds_data[i].scale may still point to a user-provided address (which could point to arbitrary kernel address), so on an error condition, this user-provided address will be freed (arbitrary free), and continued operation could result in use after free condition.

In all Qualcomm products with Android releases from CAF using the Linux kernel, in a driver function, a value from userspace is not properly validated potentially leading to an out of bounds heap write.

In all Qualcomm products with Android releases from CAF using the Linux kernel, a race condition exists in a driver potentially leading to a use-after-free condition.

In all Qualcomm products with Android releases from CAF using the Linux kernel, the camera application can possibly request frame/command buffer processing with invalid values leading to the driver performing a heap buffer over-read.

In all Qualcomm products with Android releases from CAF using the Linux kernel, a race condition exists in an IOCTL handler potentially leading to an integer overflow and then an out-of-bounds write.

In all Qualcomm products with Android releases from CAF using the Linux kernel, a race condition exists in a video driver potentially leading to a use-after-free condition.

In all Qualcomm products with Android releases from CAF using the Linux kernel, a race condition exists in a video driver which can lead to a double free.

In all Qualcomm products with Android releases from CAF using the Linux kernel, a kernel fault can occur when doing certain operations on a read-only virtual address in userspace.

In all Qualcomm products with Android releases from CAF using the Linux kernel, in some memory allocation and free functions, a race condition can potentially occur leading to a Use After Free condition.

In all Qualcomm products with Android releases from CAF using the Linux kernel, in a camera driver ioctl, a kernel overwrite can potentially occur.

In all Qualcomm products with Android releases from CAF using the Linux kernel, due to a type downcast, a value may improperly pass validation and cause an out of bounds write later.

In all Qualcomm products with Android releases from CAF using the Linux kernel, when accessing the sde_rotator debug interface for register reading with multiple processes, one process can free the debug buffer while another process still has the debug buffer in use.

In all Qualcomm products with Android releases from CAF using the Linux kernel, array out of bounds access can occur if userspace sends more than 16 multicast addresses.
