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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-416"],"references":["https://source.android.com/security/bulletin/2017-07-01","https://www.codeaurora.org/use-after-free-alsa-pcm-playback-kernel-module-cve-2017-8246","https://source.android.com/security/bulletin/2017-07-01","https://www.codeaurora.org/use-after-free-alsa-pcm-playback-kernel-module-cve-2017-8246"],"products":["google:android"],"source":"nvd","synced_at":"2026-10-19T20:42:36.429588156+00:00"},"epss":{"cve":"CVE-2017-8246","score":0.00173,"percentile":0.06763,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
