CVE-2022-49139
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: fix null ptr deref on hci_sync_conn_complete_evt This event is just specified for SCO and eSCO link types.
Does this matter?
Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.
