CVE-2015-1805
CVSS v2.0
7.2
High
| Vector | AV:L/AC:L/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 3.16
Description
The issue is related to the pipe read and pipe write implementations in fs/pipe.c, which do not properly handle the side effects of failed copy to user inatomic and copy from user inatomic calls. This can allow local users to cause a denial of service, potentially leading to a system crash, or possibly gain privileges via a crafted application. The problem is described as an "I/O vector array overrun."
Recommendations
For Linux kernel versions prior to 3.16, update to version 3.16 or later to resolve the issue. As a temporary workaround, consider restricting access to the pipe read and pipe write functions to minimize the risk of exploitation.
