In Android for MSM, Firefox OS for MSM, QRD Android, with all Android releases from CAF using the Linux kernel, concurrent rx notifications and read() operations in the G-Link PKT driver can result in a double free condition due to missing locking resulting in list_del() and list_add() overlapping and corrupting the next and previous pointers.

Weakness

The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
