CVE-2017-8246 (GCVE-0-2017-8246)

Vulnerability from cvelistv5 – Published: 2017-05-12 20:00 – Updated: 2024-08-05 16:27
VLAI
Summary
In function msm_pcm_playback_close() in all Android releases from CAF using the Linux kernel, prtd is assigned substream->runtime->private_data. Later, prtd is freed. However, prtd is not sanitized and set to NULL, resulting in a dangling pointer. There are other functions that access the same memory (substream->runtime->private_data) with a NULL check, such as msm_pcm_volume_ctl_put(), which means this freed memory could be used.
