Description OSIDB Bzimport 2024-07-30 08:36:06 UTC

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

Bluetooth: Ignore too large handle values in BIG

hci_le_big_sync_established_evt is necessary to filter out cases where the
handle value is belonging to ida id range, otherwise ida will be erroneously
released in hci_conn_cleanup.
