The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allows local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program.

The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allows local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program.
It was found that a regular user could remove xattr permissions on files by using the chown or write system calls. A local attacker could use this flaw to deny elevated permissions from valid users, services, or applications, potentially resulting in a denial of service.

CVE-2015-1350 [MEDIUM] fs: Avoid premature clearing of capabilities
fs: Avoid premature clearing of capabilities
Currently, notify_change() clears capabilities or IMA attributes by
calling security_inode_killpriv() before calling into ->setattr. Thus it
happens before any other permission checks in inode_change_ok() and user
is thus allowed to trigger clearing of capabilities or IMA attributes
for any file he can look up e.g. by calling chown for that file. This is
unexpected and can lead to user DoSing a system.
Fix the problem by calling security_inode_killpriv() at the end of
inode_change_ok() instead of from notify_change(). At that moment we are
sure user has permissions to do the requested change.

CVE-2015-1350 kernel: denial of service in notify_change for filesystem xattrs
A flaw was found where a regular user could remove xattr permissions on files by using the chown or write systemcalls. An attacker could use this feature to remove capabilities effectively denying elevated permissions to valid users. Certain services and applications require the capabilities subsystem to work correctly.

## Abstract
This paper presents a systematic study on the security of modern file systems,
following a vulnerability-centric perspective. Specifically,
we collected 377 file system vulnerabilities committed to the CVE database in the past 20 years.
We characterize them from four dimensions that include why the vulnerabilities appear,
how the vulnerabilities can be exploited, what consequences can arise,
and how the vulnerabilities are fixed. This way, we build a deep understanding of
the attack surfaces faced by file systems, the threats imposed by the attack surfaces,
and the good and bad practices in mitigating the attacks in file systems. We envision that our study
will bring insights toward
