Description
This security bulletin contains information about 1 vulnerability.
1) Information disclosure (CVE-ID: CVE-2017-7616)
CWE-ID: CWE-388 - Error Handling
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a local attacker to obtain potentially sensitive information from system memory
The weakness exists due to an error handling flaw in the set_mempolicy() and mbind compat() system calls in 'mm/mempolicy.c'. A local attacker can trigger a failure of a certain bitmap operation and obtain sensitive information from uninitialized stack data.
Successful exploitation of the vulnerability results in information disclosure.
