Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)

Description: The issue is related to a data-race condition in the ipv6 mc down function in the Linux kernel's IPv6 multicast implementation. This condition can be exploited by a remote attacker to impact the confidentiality, integrity, and availability of protected information. The vulnerability is caused by the idev->mc ifc count variable being written over without proper locking. To fix this issue, calls to mld ifc stop work() and mld gq stop work() are encapsulated with mutex lock() and mutex unlock() to ensure proper locking.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
