Description
This security bulletin contains information about 1 security vulnerability.
1) Race condition (CVE-ID: CVE-2016-10741)
The vulnerability allows a local authenticated user to perform a denial of service (DoS) attack.
In the Linux kernel before 4.9.3, fs/xfs/xfs_aops.c allows local users to cause a denial of service (system crash) because there is a race condition between direct and memory-mapped I/O (associated with a hole) that is handled with BUG_ON instead of an I/O failure.
Remediation
Install update from vendor's website.
