CVE-2026-97977

A flaw was found in the Linux kernel's Bluetooth USB driver. A race condition during device closure or disconnection allows background receive tasks to continue running after the associated device data has been released, leading to a use-after-free UAF condition. A local attacker could exploit th...

kernel: Bluetooth: btusb: revert use of devm_kzalloc in btusb

A use-after-free flaw was found in the Linux kernel's Bluetooth USB driver. The btusb driver binds to multiple USB interfaces INTF, ISOC, DIAG but allocates its data structure with devmkzalloc tied to a single interface. When that interface is released, the memory is freed while other interfaces...
