CVE-2016-0774

Date: (C)2016-04-28   (M)2017-08-02
 
CVSS Score: 5.6Access Vector: LOCAL
Exploitability Subscore: 3.9Access Complexity: LOW
Impact Subscore: 7.8Authentication: NONE
 Confidentiality: PARTIAL
 Integrity: NONE
 Availability: COMPLETE











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.
