CVE-2022-24448
First published: Fri Feb 04 2022(Updated: )
A flaw was found in the Linux kernel. When an application tries to open a directory (using the O_DIRECTORY flag) in a mounted NFS filesystem, a lookup operation is performed. If the NFS server returns a file as a result of the lookup, the NFS filesystem returns an uninitialized file descriptor instead of the expected ENOTDIR value. This flaw leads to the kernel's data leak into the userspace.
