CVE-2025-71082

The CVE affects the Linux kernel Bluetooth BTUSB path. The root cause is using devm_kzalloc in btusb_probe, which ties btusb data lifetime to a single driver interface, causing unsafe frees on disconnect when multiple interfaces exist. The fix is to revert to explicit memory freeing (don’t use de...
