CVE-2022-24448

kernel: nfs_atomic_open() returns uninitialized data instead of ENOTDIR

Published Feb 4, 2022 CVSS 3.1 · 3.3 Low EPSS < 1% KEV · Not listed
Description
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.
