CVE-2021-25457: Kernel Information Disclosure in the Vision DSP Kernel Driver
There is a sensitive information disclosure vulnerability in the vision DSP kernel driver of S20 Exynos devices. The vulnerability can be used by malicious privileged applications to read the kernel’s and other application’s memory. Vulnerability Details The Exynos DSP driver implements an ioctl call that allows applications to upload a custom model (graph) for the dsp device. The DSP_IOC_LOAD_GRAPH ioctl handler of the /dev/dsp device receives an array of Unix paths of the graph files to be loaded. This array has a complex structure, it begins with an array of integers that contains the length of each path. The array of lengths is followed by the actual path strings, one after the other, delimited by the length values.
