Description OSIDB Bzimport 2025-10-28 12:03:09 UTC

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.
