Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2017-8244. PoCs published by codecat007.

AI-analyzed exploit summary The repository contains a functional PoC for CVE-2017-8244, a race condition vulnerability in the Android kernel's msm_vidc driver. The exploit triggers the vulnerability by spawning multiple threads to read from a debug file, potentially leading to a denial-of-service or privilege escalation.

Description

In core_info_read and inst_info_read in all Android releases from CAF using the Linux kernel, variable "dbg_buf", "dbg_buf->curr" and "dbg_buf->filled_size" could be modified by different threads at the same time, but they are not protected with mutex or locks. Buffer overflow is possible on race conditions. "buffer->curr" itself could also be overwritten, which means that it may point to anywhere of kernel memory (for write).
