In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Fix UAF in channel timeout by holding conn ref… (CVE-2026-64434)CVE-2026-64434 0 A use-after-free vulnerability was identified and resolved in the Linux kernel's Bluetooth L2CAP implementation. The issue occurs because the asynchronous l2cap_chan_timeout() function accesses a connection object that may have been freed if the connection is torn down while the timer is pending. This can lead to a use-after-free condition when the timer worker attempts to lock the freed connection's mutex. The fix involves holding a reference to the connection object for the lifetime of the channel to prevent premature freeing.
