A\n64-Tx/64-Rx configuration therefore records 128 vectors but allocates\nonly 64, leaving NULL entries that resource setup dereferences.\n\nInclude the maximum vector count in standalone allocation.","modified":"2026-10-20T02:30:54.851306845Z","published":"2026-10-18T15:19:38.631Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98618.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/16ff1023213cc39c1a7ce737205c2a1a53c3a716"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1f4c73064a50f53d596c6f1d06d2d700f43c4b32"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6c903188b67617070017305a325fa326f270a43d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9843e5fabd6ab296df9c025b1d0e5bf79a6b8a08"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98618.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98618"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"bc6107771bb4be3009168cfda24d22131c026fe8"},{"fixed":"9843e5fabd6ab296df9c025b1d0e5bf79a6b8a08"},{"fixed":"6c903188b67617070017305a325fa326f270a43d"},{"fixed":"16ff1023213cc39c1a7ce737205c2a1a53c3a716"},{"fixed":"1f4c73064a50f53d596c6f1d06d2d700f43c4b32"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98618.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.11.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.55"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98618.json"}}],"schema_version":"1.9.0"}
