The vulnerability of the Direct IO function in Linux operating system kernels allows attackers to gain unauthorized access to protected information or cause service failures.

The vulnerability of the Direct IO function in Linux operating systems lies in the fact that operations are performed outside the buffer boundaries. Exploiting this vulnerability can allow an attacker to gain unauthorized access to protected information or cause service failures...

DEBIAN-CVE-2016-10741

In the Linux kernel before 4.9.3, fs/xfs/xfsaops.c allows local users to cause a denial of service system crash because there is a race condition between direct and memory-mapped I/O associated with a hole that is handled with BUGON instead of an I/O failure...

DEBIAN-CVE-2017-18204

The ocfs2setattr function in fs/ocfs2/file.c in the Linux kernel before 4.14.2 allows local users to cause a denial of service deadlock via DIO requests...

UBUNTU-CVE-2017-18204

The ocfs2setattr function in fs/ocfs2/file.c in the Linux kernel before 4.14.2 allows local users to cause a denial of service deadlock via DIO requests...

kernel: race condition between direct and memory-mapped I/O in fs/xfs/xfs_aops.c

It was found that the Linux kernel can hit a BUGON statement in the xfsgetblocks in the fs/xfs/xfsaops.c because of a race condition between direct and memory-mapped I/O associated with a hole in a file that is handled with BUGON instead of an I/O failure. This allows a local unprivileged attacke...

DEBIAN-CVE-2014-8086

Race condition in the ext4filewriteiter function in fs/ext4/file.c in the Linux kernel through 3.17 allows local users to cause a denial of service file unavailability via a combination of a write action and an FSETFL fcntl operation for the ODIRECT flag...

UBUNTU-CVE-2014-8086

Race condition in the ext4filewriteiter function in fs/ext4/file.c in the Linux kernel through 3.17 allows local users to cause a denial of service file unavailability via a combination of a write action and an FSETFL fcntl operation for the ODIRECT flag...

kernel: cifs oops when creating file with O_DIRECT set

The cifsclose function in fs/cifs/file.c in the Linux kernel before 2.6.39 allows local users to cause a denial of service NULL pointer dereference and BUG or possibly have unspecified other impact by setting the ODIRECT flag during an attempt to open a file on a CIFS filesystem...

kernel: dio: zero struct dio with kzalloc instead of manually

fs/direct-io.c in the dio subsystem in the Linux kernel before 2.6.23 does not properly zero out the dio struct, which allows local users to cause a denial of service OOPS, as demonstrated by a certain fio test...

security flaw

Memory leak in direct-io.c in Linux kernel 2.6.x before 2.6.10 allows local users to cause a denial of service memory consumption via certain ODIRECT direct IO write requests...

security flaw

Linux kernel before 2.6.13 allows local users to cause a denial of service crash via a dio transfer from the sg driver to memory mapped mmap IO space...

security flaw

Unknown vulnerability in Linux kernel 2.4.x, 2.5.x, and 2.6.x allows NFS clients to cause a denial of service via ODIRECT...
