CVE-2026-97977

The Linux kernel contains a Use-After-Free (UAF) vulnerability in the btusb Bluetooth driver. The issue occurs because btusb_close() and btusb_flush() use the asynchronous cancel_delayed_work() function; if btusb_rx_work() is already executing on another CPU, it continues running after the cancel...

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...

CVE-2026-68339

A flaw was found in the Linux kernel's Bluetooth subsystem btusb driver. An attacker could craft a two-byte vendor event that, due to improper validation of the Realtek vendor event length in the btusbrecveventrealtek function, could lead to the system attempting to read a non-existent third byte...
