Overview

CVE-2023-54164 is a high-severity vulnerability. It was published on December 30, 2025 and has a CVSS 3.1 base score of 8.0 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.0, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: ISO: fix iso_conn related locking and validity issues

sk->sk_state indicates whether iso_pi(sk)->conn is valid. Operations

that check/update sk_state and access conn should hold lock_sock,

otherwise they can race.

The order of taking locks is hci_dev_lock > lock_sock > iso_conn_lock,

which is how it is in connect/disconnect_cfm -> iso_conn_del ->

iso_chan_del.

Fix locking in iso_connect_cis/bis and sendmsg/recvmsg to take lock_sock

around updating sk_state and conn.

iso_conn_del must not occur during iso_connect_cis/bis, as it frees the

iso_conn. Hold hdev->lock longer to prevent that.

This should not reintroduce the issue fixed in commit 241f51931c35

("Bluetooth: ISO: Avoid circular locking dependency"), since the we

acquire locks in order. We retain the fix in iso_sock_connect to release

lock_sock before iso_connect_* acquires hdev->lock.

Similarly for commit 6a5ad251b7cd ("Bluetooth: ISO: Fix possi
