CVE-2025-40055

Estado: AplazadaSin puntuar—

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.
