{"id":"CVE-2019-17075","details":"An issue was discovered in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel through 5.3.2. The cxgb4 driver is directly calling dma_map_single (a DMA function) from a stack variable. This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used on an architecture for which this stack/DMA interaction has security relevance.","modified":"2026-03-15T22:30:55.098030Z","published":"2019-10-01T21:15:11.523Z","references":[{"type":"WEB","url":"https://lore.kernel.org/lkml/20191001165611.GA3542072%40kroah.com"},{"type":"ADVISORY","url":"http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4210-1/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4211-1/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4211-2/"},{"type":"ADVISORY","url":"https://www.oracle.com/security-alerts/cpuApr2021.html"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html"},{"type":"ADVISORY","url":"https://seclists.org/bugtraq/2019/Nov/11"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4208-1/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4226-1/"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"2.6.35"},{"fixed":"4.4.198"}]},{"events":[{"introduced":"4.5.0"},{"fixed":"4.9.198"}]},{"events":[{"introduced":"4.10"},{"fixed":"4.14.151"}]},{"events":[{"introduced":"4.15"},{"fixed":"4.19.81"}]},{"events":[{"introduced":"4.20"},{"fixed":"5.3.8"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-17075.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
