{"id":"DEBIAN-CVE-2024-46690","details":"In the Linux kernel, the following vulnerability has been resolved:  nfsd: fix nfsd4_deleg_getattr_conflict in presence of third party lease  It is not safe to dereference fl-\u003ec.flc_owner without first confirming fl-\u003efl_lmops is the expected manager.  nfsd4_deleg_getattr_conflict() tests fl_lmops but largely ignores the result and assumes that flc_owner is an nfs4_delegation anyway.  This is wrong.  With this patch we restore the \"!= &nfsd_lease_mng_ops\" case to behave as it did before the change mentioned below.  This is the same as the current code, but without any reference to a possible delegation.","modified":"2026-09-15T09:03:09.741711440Z","published":"2024-09-13T06:15:13.753Z","upstream":["CVE-2024-46690"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-46690"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.10.9-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-46690.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.10.9-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2024-46690.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
