Recommendation: Monitor — no exploitation signal at the moment.
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: fix double free in user_cluster_connect()
user_cluster_disconnect() frees "conn->cc_private" which is "lc" but then
the error handling frees "lc" a second time. Set "lc" to NULL on this
path to avoid a double free.
