# CVE-2017-8244: 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\_b

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Published: 2017-05-12 · Updated: 2024-08-05

## Affected

- Qualcomm, Inc. Android for MSM, Firefox OS for MSM, QRD Android: version range not reported

## 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).
