{"id":"CVE-2026-64519","summary":"NFSD: Fix infinite loop in layout state revocation","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nNFSD: Fix infinite loop in layout state revocation\n\nfind_one_sb_stid() skips stids whose sc_status is non-zero, but the\nSC_TYPE_LAYOUT case in nfsd4_revoke_states() never sets sc_status\nbefore calling nfsd4_close_layout(). The retry loop therefore finds\nthe same layout stid on every iteration, hanging the revoker\nindefinitely.","modified":"2026-07-27T03:47:26.184557996Z","published":"2026-07-25T09:14:45.322Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64519.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/44e5e4eb3a07bf3e1d931dd9f96f3edcfa376605"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4f8ef58c10bfe5f86a643c7c8331b37e69e3dae1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d1fc00ec02e9deb3f8d2bd59caf938c554fbc576"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fe59ae27d7346245f5d8d97220f374e63efd28b5"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64519.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64519"},{"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":"1e33e1414bec54a4feafa9e67e2617031be0afe2"},{"fixed":"d1fc00ec02e9deb3f8d2bd59caf938c554fbc576"},{"fixed":"fe59ae27d7346245f5d8d97220f374e63efd28b5"},{"fixed":"44e5e4eb3a07bf3e1d931dd9f96f3edcfa376605"},{"fixed":"4f8ef58c10bfe5f86a643c7c8331b37e69e3dae1"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-64519.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.9.0"},{"fixed":"6.12.92"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.34"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-64519.json"}}],"schema_version":"1.7.5"}
