{"id":"CVE-2023-2194","details":"An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The userspace \"data-\u003eblock[0]\" variable was not capped to a number between 0-255 and was used as the size of a memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to crash the system or potentially achieve code execution.","modified":"2026-03-15T22:01:00.759571Z","published":"2023-04-20T21:15:09.047Z","related":["ALSA-2023:3708","ALSA-2023:3723","ALSA-2023:4517","ALSA-2023:4541","SUSE-SU-2023:2501-1","SUSE-SU-2023:2502-1","SUSE-SU-2023:2507-1","SUSE-SU-2023:2534-1","SUSE-SU-2023:2537-1","SUSE-SU-2023:2538-1","SUSE-SU-2023:2611-1","SUSE-SU-2023:2651-1","SUSE-SU-2023:2805-1"],"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2023/05/msg00005.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2023/05/msg00006.html"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2188396"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/92fbb6d1296f"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-2194.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"6.3"}]},{"events":[{"introduced":"0"},{"last_affected":"6.3-rc1"}]},{"events":[{"introduced":"0"},{"last_affected":"6.3-rc2"}]},{"events":[{"introduced":"0"},{"last_affected":"6.3-rc3"}]},{"events":[{"introduced":"0"},{"last_affected":"38"}]},{"events":[{"introduced":"0"},{"last_affected":"8.0"}]},{"events":[{"introduced":"0"},{"last_affected":"9.0"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"}]}
