{"id":"CVE-2026-93188","summary":"HID: roccat: bound device-supplied profile index","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nHID: roccat: bound device-supplied profile index\n\nkone_keep_values_up_to_date() and kone_profile_activated() use an\n8-bit, device-supplied profile value as an index into the 5-element\nkone-\u003eprofiles[] array without a range check. A malicious USB device\nclaiming the Roccat Kone id can send a switch-profile event (or a\nstartup_profile read at probe) with an out-of-range value and make the\ndriver read out of bounds; the result is exposed via the actual_dpi\nsysfs attribute.\n\nReject out-of-range indices in both paths.\n\nThis was found with static analysis and confirmed with the KUnit test\nadded in the following patch (KASAN: slab-out-of-bounds).","modified":"2026-09-19T03:47:28.317270330Z","published":"2026-09-17T16:12:13.482Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93188.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0a139188a7ce4baab7acc5d60e0d1c8657f9b4d4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/43fae42628a8c10fa8981773d7ec9f1a367821a7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4b29be4b23bc28f59def1485702887e395256e11"},{"type":"WEB","url":"https://git.kernel.org/stable/c/579c78c8c317ecff8b6b820c227c93e6ec4e565d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/635914c60da26a9892f27ffb5edcc922a10effab"},{"type":"WEB","url":"https://git.kernel.org/stable/c/67d7851f113fd0205dd27416d3c47ab32b176097"},{"type":"WEB","url":"https://git.kernel.org/stable/c/686e5c3bd378933b4e795fcc7d40c5aad358eaaa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/99330b12376c3373ab555c24bc797630f03b81a2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93188.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93188"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"14bf62cde79423a02a590e02664ed29a36facec1"},{"fixed":"686e5c3bd378933b4e795fcc7d40c5aad358eaaa"},{"fixed":"0a139188a7ce4baab7acc5d60e0d1c8657f9b4d4"},{"fixed":"67d7851f113fd0205dd27416d3c47ab32b176097"},{"fixed":"4b29be4b23bc28f59def1485702887e395256e11"},{"fixed":"579c78c8c317ecff8b6b820c227c93e6ec4e565d"},{"fixed":"635914c60da26a9892f27ffb5edcc922a10effab"},{"fixed":"99330b12376c3373ab555c24bc797630f03b81a2"},{"fixed":"43fae42628a8c10fa8981773d7ec9f1a367821a7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93188.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.35"},{"fixed":"5.10.270"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.221"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93188.json"}}],"schema_version":"1.9.0"}
