Vulnerability Name:

CVE-2022-24448 (CCN-218947)

Assigned:2022-01-07
Published:2022-01-07
Updated:2022-05-12
Summary:An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor.
