{"id":"CVE-2026-90148","summary":"NFSv4: Fix incorrect argument passed to nfs4_delete_lease() in nfs4_add_lease()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nNFSv4: Fix incorrect argument passed to nfs4_delete_lease() in nfs4_add_lease()\n\nWhen nfs4_add_lease() races with a delegation return, it calls\nnfs4_delete_lease() to clean up. Previously, it passed priv,\nwhich can legitimately be NULL. Passing a NULL priv eventually\nleads to a NULL pointer dereference in generic_setlease().","modified":"2026-09-18T03:48:35.734163849Z","published":"2026-09-17T16:06:42.992Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90148.json"},"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/468e458ffde907ba19acd2102ca1fbb8f6fbede2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d148a652d52fd6aee96daf798922eb800ebb3018"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d179ff22cd8514f966966fd9ad425dcbb98e1ada"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ff7244faa13b23e9acfad9df0438f0b44b338f62"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90148.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90148"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e93a5e9306a576011f03011b492d4fbaa274477b"},{"fixed":"ff7244faa13b23e9acfad9df0438f0b44b338f62"},{"fixed":"d148a652d52fd6aee96daf798922eb800ebb3018"},{"fixed":"d179ff22cd8514f966966fd9ad425dcbb98e1ada"},{"fixed":"468e458ffde907ba19acd2102ca1fbb8f6fbede2"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90148.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.14.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90148.json"}}],"schema_version":"1.9.0"}
