But this may\nlead to a UAF because the accessed runtime->dma_area might be freed\nconcurrently, as it's performed outside the PCM ops.\n\nFor avoiding it, move the code into the PCM core and perform it inside\nthe buffer access lock, so that it won't be changed during the\noperation.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","score":4.7},"cwes":["CWE-362"],"references":["https://git.kernel.org/stable/c/10217da9644ae75cea7330f902c35fc5ba78bbbf","https://git.kernel.org/stable/c/74d90875f3d43f3eff0e9861c4701418795d3455","https://git.kernel.org/stable/c/8170d8ec4efd0be352c14cb61f374e30fb0c2a25","https://git.kernel.org/stable/c/93a81ca0657758b607c3f4ba889ae806be9beb73","https://git.kernel.org/stable/c/afa56c960fcb4db37f2e3399f28e9402e4e1f470"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:03:23.287444849+00:00"},"epss":{"cve":"CVE-2025-38078","score":0.00155,"percentile":0.04579,"date":"2026-10-25"},"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).
