Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains an issue related to Bluetooth handling. Specifically, the scheduling of work items within the Bluetooth HCI (Host Controller Interface) subsystem was flawed. A check intended to prevent improper work queueing during draining operations was incomplete, potentially leading to issues when queuing timer works. The problem arises from attempting to schedule work from a system workqueue into a workqueue that is undergoing a draining operation. This was identified by syzbot and addressed with code changes to ensure the correct workqueue is used and to protect the queuing operation with a read lock.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
