Detailsinfo

A vulnerability was found in Red Hat Enterprise Linux up to 7.1 (Operating System) and classified as critical. This issue affects the function pipe_read/pipe_write of the file fs/pipe.c. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The (1) pipe_read and (2) pipe_write implementations in fs/pipe.c in a certain Linux kernel backport in the linux package before 3.2.73-2+deb7u3 on Debian wheezy and the kernel package before 3.10.0-229.26.2 on Red Hat Enterprise Linux (RHEL) 7.1 do not properly consider the side effects of failed __copy_to_user_inatomic and __copy_from_user_inatomic calls, which allows local users to cause a denial of service (system crash) or possibly gain privileges via a crafted application, aka an "I/O vector array overrun." NOTE: this vulnerability exists because of an incorrect fix for CVE-2015-1805.

The weakness was shared 04/27/2016 with Red Hat (Website). The advisory is shared at security-tracker.debian.org. The identification of this vulnerability is CVE-2016-0774 since 12/15/2015. An attack has to be approached locally. Required for exploitation is a simple authentication. Technical details are known, but no exploit is available.
