Use check_add_overflow() as is already done for the\nadjacent prev_lcn + dlcn and vcn64 + len checks added by commit\n3ac37e100385 (\"ntfs3: Fix integer overflow in run_unpack()\").\n\nFound by fuzzing with a source-patched harness (LibAFL + QEMU).","modified":"2026-06-18T03:56:48.718736714Z","published":"2026-05-27T12:57:24.416Z","related":["openSUSE-SU-2026:10954-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46062.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/424858f9a048057bb8f834bfe03d18f5e477e747"},{"type":"WEB","url":"https://git.kernel.org/stable/c/60dab3e2931f3d792438a77a6cb0cb731c43300b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6175d09c23bec4b60860ee9a0170308ff4b56e10"},{"type":"WEB","url":"https://git.kernel.org/stable/c/984a415f019536ea2d24de9010744e5302a9a948"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a954061b334ec67c79ae9d0cadd83fa521396487"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e73cd5aed6b15e55c1c47577bdb473b5e88d6a69"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f1af27cec07a9fd0847166bdb23c99e86b05bfdc"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46062.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46062"},{"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":"82cae269cfa953032fbb8980a7d554d60fb00b17"},{"fixed":"424858f9a048057bb8f834bfe03d18f5e477e747"},{"fixed":"e73cd5aed6b15e55c1c47577bdb473b5e88d6a69"},{"fixed":"a954061b334ec67c79ae9d0cadd83fa521396487"},{"fixed":"60dab3e2931f3d792438a77a6cb0cb731c43300b"},{"fixed":"f1af27cec07a9fd0847166bdb23c99e86b05bfdc"},{"fixed":"6175d09c23bec4b60860ee9a0170308ff4b56e10"},{"fixed":"984a415f019536ea2d24de9010744e5302a9a948"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46062.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.15.0"},{"fixed":"5.15.209"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.175"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.140"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.86"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.27"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46062.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
