Description
This security bulletin contains information about 1 security vulnerability.
1) Resource management error (CVE-ID: CVE-2016-10153)
The vulnerability allows a local authenticated user to execute arbitrary code.
The crypto scatterlist API in the Linux kernel 4.9.x before 4.9.6 interacts incorrectly with the CONFIG_VMAP_STACK option, which allows local users to cause a denial of service (system crash or memory corruption) or possibly have unspecified other impact by leveraging reliance on earlier net/ceph/crypto.c code.
Remediation
Install update from vendor's website.
