Attackers can supply crafted topology files that wrap size calculations, causing the decoder to read beyond the topology buffer and potentially leak sensitive data or crash the application.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N","score":4.8},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L","score":4.4},"cwes":["CWE-190"],"references":["https://github.com/alsa-project/alsa-lib","https://github.com/alsa-project/alsa-lib/blob/v1.2.16.1/src/topology/ctl.c#L1316-L1326","https://github.com/alsa-project/alsa-lib/blob/v1.2.16.1/src/topology/ctl.c#L1420-L1430","https://github.com/alsa-project/alsa-lib/blob/v1.2.16.1/src/topology/ctl.c#L1511-L1521","https://github.com/alsa-project/alsa-lib/pull/527"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-96674","score":0.00115,"percentile":0.01544,"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).
