In all Qualcomm products with Android releases from CAF using the Linux kernel, in function msm_compr_ioctl_shared, variable "ddp->params_length" could be accessed and modified by multiple threads, while it is not protected with locks. If one thread is running, while another thread is setting data, race conditions will happen. If "ddp->params_length" is set to a big number, a buffer overflow will occur. En la función msm_compr_ioctl_shared en todos los productos Qualcomm con distribuciones Android desde CAF empleando el kernel Linux, se podría acceder a la variable "ddp->params_length" y modificarla empleando múltiples subprocesos, siempre y cuando no esté protegida por locks. Si un subproceso se está ejecutando mientras otro establece los datos, ocurrirá una condición de carrera. • http://www.securityfocus.com/bid/100658 https://source.android.com/security/bulletin/2017-09-01 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
