The memcpy() at the bottom fills only the\nfirst 28 bytes (TEMP + 6 channels of GYRO/ACCEL data), and\niio_push_to_buffers_with_timestamp() writes the s64 timestamp at the\n8-byte-aligned offset 32.  Bytes 28-31 remain uninitialized stack data\nwhich leaks to userspace on ever trigger.\n\nFix this all by just zero-initializing the structure on the stack.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-401"],"references":["https://git.kernel.org/stable/c/474f8928d50b09f7dcf507049f08732640b88b49","https://git.kernel.org/stable/c/c2c255444392872cbbf46d640cb3a938e8000309","https://git.kernel.org/stable/c/ce582b22dd2ff15ac99101c22ec1559d1febe2ff"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-30T17:45:53.525042316+00:00"},"epss":{"cve":"CVE-2026-63966","score":0.00206,"percentile":0.10759,"date":"2026-10-30"},"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).
