CVE-2025-71090

CVE-2025-71090 describes a Linux kernel NFS daemon leak in nfsd4_add_rdaccess_to_wrdeleg(). The function overwrites fp->fi_fds[O_RDONLY] with a new nfsd_file even when a SHARE_ACCESS_READ is already open, thereby orphaning the prior reference. It previously stored the same nfsd_file pointer in...

CVE-2025-68803

In CVE-2025-68803, the Linux kernel NFSD shows a flaw in NFSv4 file creation: when a client sets a named-ACL during creation, the ACL is not applied because nfsd_attrs_valid() ignores POSIX ACLs, causing nfsd_setattr() to be skipped. As a result, the ACL stored on the inode may be generated from ...
