| Vector | AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
linux package versions prior to 3.2.73-2+deb7u3
linux package versions prior to 3.10.0-229.26.2 on Red Hat Enterprise Linux (RHEL) 7.1
Description
The issue is related to the
pipe read and pipe write implementations in fs/pipe.c in certain Linux kernel backports. It allows local users to cause a denial of service (system crash) or possibly gain privileges via a crafted application. This is due to the improper consideration of side effects from failed copy to user inatomic and copy from user inatomic calls, leading to an "I/O vector array overrun."Recommendations
For linux package versions prior to 3.2.73-2+deb7u3, update to version 3.2.73-2+deb7u3 or later to resolve the issue.
For linux package versions prior to 3.10.0-229.26.2 on Red Hat Enterprise Linux (RHEL) 7.1, update to version 3.10.0-229.26.2 or later to resolve the issue.
