CVE-2025-40284

CVE-2025-40284 affects the Linux kernel Bluetooth MGMT path. The mesh_send_done timer was not canceled when the hdev was removed, causing a use-after-free crash (KASAN) after the timer could fire. A fix cancels the mesh_send_done timer during MGMT hdev removal, aligning with other MGMT timers. Th...

CVE-2025-40283

CVE-2025-40283 concerns the Linux kernel Bluetooth driver btusb (btusb_disconnect) where cleanup is performed in the wrong order, leading to a use-after-free (UAF) of btusb data after usb_driver_release_interface frees the interface data. The issue is observed as a KASAN slab-use-after-free read ...

CVE-2025-40282

In CVE-2025-40282, the Linux kernel Bluetooth 6lowpan implementation (net/bluetooth/6lowpan.c) is affected. The issue arises because netdev header_ops requires a link-local MAC header on RX skb, but the code resets this header only for the uncompressed IPv6 RX path; the compressed path already ha...
