CVE-2017-8244 is a race condition vulnerability in Android releases from CAF using the Linux kernel, specifically within the core_info_read and inst_info_read functions. This flaw allows for a buffer overflow due to unprotected concurrent modifications of critical buffer variables, potentially leading to arbitrary kernel memory writes. Rated 7.0 HIGH, it requires local access and high attack complexity but can result in complete compromise of confidentiality, integrity, and availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.

CVE-2017-8244
Sep 8, 2020In 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).
