Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.11.8
Description
The issue is related to the
snd msnd interrupt function in the Linux kernel, which allows local users to cause a denial of service or possibly have other unspecified impacts. This is due to a "double fetch" vulnerability, where the value of a message queue head pointer can be changed between two kernel reads, resulting in over-boundary access. The vulnerability may be exploited to cause a denial of service or other effects.Recommendations
For Linux kernel versions prior to 4.11.8, update to version 4.11.8 or later to resolve the issue. As a temporary workaround, consider restricting access to the
snd msnd interrupt function to minimize the risk of exploitation.Correção
