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":"2026-08-28T17:47:44.456331504Z","published":"2026-05-27T14:17:26Z","upstream":["CVE-2026-46062"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46062"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.141.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-88650.json"}}],"schema_version":"1.9.0"}
