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.","affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e4570f4bb231f01e32d44fd38841665f340d6914"},{"fixed":"ce582b22dd2ff15ac99101c22ec1559d1febe2ff"},{"fixed":"c2c255444392872cbbf46d640cb3a938e8000309"},{"fixed":"474f8928d50b09f7dcf507049f08732640b88b49"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-63966.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.15.0"},{"fixed":"6.18.35"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.12"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-63966.json"}}],"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/474f8928d50b09f7dcf507049f08732640b88b49"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c2c255444392872cbbf46d640cb3a938e8000309"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ce582b22dd2ff15ac99101c22ec1559d1febe2ff"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63966.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63966"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63966.json"}}
