CVE-2026-74508

CVE-2026-74508 affects the Linux kernel Bluetooth HIDP path. The bug occurs in hidp_recv_ctrl_frame() and hidp_recv_intr_frame(): they read skb->data[0] before verifying the L2CAP SDU header, enabling an uninitialized-byte use from skb tailroom when an empty basic-mode SDU is received or when ...

CVE-2026-74509

The CVE applies to the Linux kernel Bluetooth HCI path for extended advertising. Root cause: hci_find_adv_instance() can return an adv_info pointer that remains valid only while hdev->lock is held, but advertisement data paths perform lookups without that lock and may retain the pointer while ...
