CVE-2022-48982

CVE-2022-48982 affects the Linux kernel Bluetooth subsystem, specifically CSR fake controllers. The issue arises when a CSR 5.0 clone causes the suspend notifier to be registered twice, which can lead to a kernel panic during Bluetooth device probing (btusb/hci stack). The connected advisories an...
