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.
Affected configurations
• linux linux kernel (< 5.16.5)
• debian debian linux 9.0
• debian debian linux 10.0
• debian debian linux 11.0
