The userspace \"data->block[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.","affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/torvalds/linux","events":[{"introduced":"197b6b60ae7bc51dd0814953c562833143b292aa"},{"last_affected":"197b6b60ae7bc51dd0814953c562833143b292aa"}],"database_specific":{"extracted_events":[{"introduced":"Fixed in kernel v6.3-rc4"},{"last_affected":"Fixed in kernel v6.3-rc4"}],"source":"AFFECTED_FIELD"}}],"versions":["Fixed in kernel v6.3-rc4","v6.3-rc4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-2194.json"}}],"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/2xxx/CVE-2023-2194.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-2194"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2188396"},{"type":"FIX","url":"https://github.com/torvalds/linux/commit/92fbb6d1296f"},{"type":"ARTICLE","url":"https://lists.debian.org/debian-lts-announce/2023/05/msg00005.html"},{"type":"ARTICLE","url":"https://lists.debian.org/debian-lts-announce/2023/05/msg00006.html"}],"database_specific":{"cna_assigner":"redhat","cwe_ids":["CWE-787"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/2xxx/CVE-2023-2194.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"}]}
