In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_conn: Use disable_delayed_work_sync
This makes use of disable_delayed_work_sync instead
cancel_delayed_work_sync as it not only cancel the ongoing work but also
disables new submit which is disarable since the object holding the work
is about to be freed.

a specially crafted file system image that, when mounted, could cause a
denial of service (system crash) or possibly execute arbitrary code.

CVE-2024-56591 [MEDIUM] CWE-99 kernel: Bluetooth: hci_conn: Use disable_delayed_work_sync
kernel: Bluetooth: hci_conn: Use disable_delayed_work_sync
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_conn: Use disable_delayed_work_sync
This makes use of disable_delayed_work_sync instead
cancel_delayed_work_sync as it not only cancel the ongoing work but also
disables new submit which is disarable since the object holding the work
is about to be freed.
A flaw was found in the Bluetooth subsystem of the Linux kernel, in the handling of delayed work within the hci_conn (Host Controller Interface connection) structure. The kernel used cancel_delayed_work_sync() when shutting down a connection, which cancels ongoing work but allows rescheduling. This could result in use-after-free conditions if the work is resubmitted after the associated object has

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
