CVE-2025-40141 is a possible use-after-free vulnerability in the Linux kernel Bluetooth ISO subsystem. Failure to clear the conn->sk pointer to NULL can lead to a use-after-free in iso_conn_free during connection cleanup. The flaw is analogous to an issue involving sco_conn_free and may result in kernel memory corruption or denial of service, with kernel-context arbitrary code execution identified as a possible but unconfirmed consequence.
