CVE-2025-40141 is a use-after-free vulnerability in the Linux kernel Bluetooth Isochronous Channels (ISO) subsystem. During ISO connection cleanup, the connection object's socket reference may remain non-NULL when the connection is freed. Subsequent access through that stale reference can dereference freed memory, producing a use-after-free condition. The flaw is analogous to a previously addressed Bluetooth SCO connection-cleanup issue.
