In wacom_hid_set_device_mode(), use\nthis stored field index to access the correct field and add bounds\nchecks to ensure both the field index and the value index are within\nvalid ranges before writing.","affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5ae6e89f7409cb5d218bb728326eba9c650d9700"},{"fixed":"2add311d99646c9d235b2c44f9c169ba30f5db3a"},{"fixed":"83bd8a5756a3c4a413ed8f6253f9eb2821e1ccaf"},{"fixed":"5716a293fb19d382ca2336e08fd28a619a5f3c25"},{"fixed":"ed598de9f61582902406d352d99f2073d8e00298"},{"fixed":"43e7c02d6090a82fd60d63491f6871aec906345e"},{"fixed":"b8338111e14183972359009c12d0dbd81d2e1e16"},{"fixed":"5db3fca0cec7b33bc5379411d0a60d792c9f9bc0"},{"fixed":"c0a8899e02ddebd51e2589835182c239c2e224ae"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-63916.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.18.0"},{"fixed":"5.10.259"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.210"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.176"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.143"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.93"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"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-2026-63916.json"}}],"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2add311d99646c9d235b2c44f9c169ba30f5db3a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/43e7c02d6090a82fd60d63491f6871aec906345e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5716a293fb19d382ca2336e08fd28a619a5f3c25"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5db3fca0cec7b33bc5379411d0a60d792c9f9bc0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/83bd8a5756a3c4a413ed8f6253f9eb2821e1ccaf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b8338111e14183972359009c12d0dbd81d2e1e16"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c0a8899e02ddebd51e2589835182c239c2e224ae"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ed598de9f61582902406d352d99f2073d8e00298"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63916.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63916"},{"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-2026-63916.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
