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-2026-63915
In the Linux kernel, the following vulnerability has been resolved: nfc: hci: fix out-of-bounds read in HCP header parsing Both nfchcirecvfromllc and ncihcidatareceivedcb read packet-header from skb-data at function entry without first checking that the buffer holds at least one byte. A malicious...
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...
