However, because the driver allocates a fixed 4K buffer for\nthe PRP list, accommodating at most 512 entries, the driver supports a\nmaximum I/O transfer size of 2 MiB.\n\nLimit max_hw_sectors to the smaller of the reported MDTS and the 2 MiB\ndriver limit to prevent issuing oversized I/O that may lead to a kernel\noops.","modified":"2026-07-15T01:49:12.277992874Z","published":"2026-05-28T09:35:09.126Z","related":["openSUSE-SU-2026:10954-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46105.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/04631f55afc543d5431a2bdee7f6cc0f2c0debe7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/45dcc815fc5539e88154315f36cbcb11d3a52fc2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e5f9824817c6358b9f9738bdb92dec9e4e794d3c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46105.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46105"},{"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":"9b8b84879d4adc506b0d3944e20b28d9f3f6994b"},{"fixed":"45dcc815fc5539e88154315f36cbcb11d3a52fc2"},{"fixed":"e5f9824817c6358b9f9738bdb92dec9e4e794d3c"},{"fixed":"04631f55afc543d5431a2bdee7f6cc0f2c0debe7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46105.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.17.0"},{"fixed":"6.18.30"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46105.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
