Описание
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: hold hdev->lock for hci_conn_params lookups
hci_conn_params_lookup requires hdev->lock be held, otherwise the list
iteration or param access is not safe.
Hold hdev->lock for params lookups in hci_sync.
A flaw was found in the Linux kernel's Bluetooth subsystem, specifically within the hci_sync component. This vulnerability occurs because the hci_conn_params_lookup function does not properly hold a necessary lock (hdev->lock) during operations. This oversight can lead to unsafe list iterations or parameter access, potentially resulting in data corruption or system instability.
