Description
This security bulletin contains information about 1 vulnerability.
1) Memory leak (CVE-ID: CVE-2016-0774)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local attacker to cause DoS condition or gain elevated privileges on the target system.
The weakness exists in the (1) pipe_read and (2) pipe_write implementations in fs/pipe.c due to improper consideration of the side effects of failed __copy_to_user_inatomic and __copy_from_user_inatomic calls. A local attacker can trigger memory leak, cause the service to crash or gain root privileges.
