In the Linux kernel, the following vulnerability has been resolved: mptcp: fix stale skb-sk reference on subflow close The backlog list is updated by mptcpdataready under mptcpdatalock. The cleanup of backlog references to a closing subflow, however, was performed in mptcpclosessk, before...

CVE-2026-68170

CVE-2026-68170, affecting Linux kernel MPTCP, describes a use-after-free risk caused by a stale backlog backlog entry referencing a closing subflow. The issue arises because backlog cleanup was performed in mptcp_close_ssk() without holding the ssk lock or mptcp_data_lock(), while concurrent RX p...

CVE-2026-68146

The CVE-2026-68146 entry documents a Linux kernel ftrace vulnerability where the trace_parser state (idx, cont, buffer) could race when multiple threads share an open trace file descriptor and perform concurrent writes or releases. The fix introduces a global mutex (parser_lock) to serialize all ...
