CVE-2026-63915

A flaw was found in the Linux kernel's Near Field Communication NFC Host Controller Interface HCI. A remote attacker, by sending a specially crafted 0-byte Host Controller Protocol HCP frame, could trigger an out-of-bounds read. This could lead to a system crash, resulting in a Denial of Service...

CVE-2026-63974

CVE-2026-63974 affects the Linux kernel Bluetooth subsystem. The issue arises in hci_sync where HCI_CMD_DRAIN_WORKQUEUE must be set during device close because hci_dev_close_sync() can be invoked on a reset path, preventing timeouts from being queued while the hdev workqueue drains. The consequen...
