Vulnerability from fkie_nvd - Published: 2009-05-14 17:30 - Updated: 2025-04-09 00:30
Severity ?
Summary
The nfs_permission function in fs/nfs/dir.c in the NFS client implementation in the Linux kernel 2.6.29.3 and earlier, when atomic_open is available, does not check execute (aka EXEC or MAY_EXEC) permission bits, which allows local users to bypass permissions and execute files, as demonstrated by files on an NFSv4 fileserver.
