CVE-2024-46690 is fixed in linux on 1 platform, first by DEBIAN-CVE-2024-46690, released September 13, 2024. It is not reported as exploited. Patch Radar priority: Routine.
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->c.flc_owner without first confirming fl->fl_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.
