That fits dma_direct_alloc(), but\ndma_direct_alloc_pages() also uses the helper and expects a struct page *.\n\nFix this by making dma_direct_alloc_from_pool() return the struct page *\nagain, and pass the CPU address back through an out-parameter for the\ndma_direct_alloc() caller.","published":"2026-09-16T10:33:07.962Z","modified":"2026-09-18T03:48:34.593189171Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.12.110"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/408ff2d5bf555bd3f4c84a2edb95c0690bf9edc8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/94a04ad732c9f8b9554270fc4038a06737de5c22"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c3fdb94da43ff23287f85664174c45c45e881a3f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/feeb2ef775081a6c188cdd10e7a45369a07ce531"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89995.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89995"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-18T03:48:34.593189171Z"}}
