CVE-2026-98296

A vulnerability exists in the Linux kernel 's Bluetooth btintel_pcie driver. The function btintel_pcie_prepare_tx() performs an unchecked memcpy to copy skb->len bytes into a fixed DMA slot of 4096 bytes. While oversized packets are currently rejected in btintel_pcie_send_frame(), any future c...

CVE-2026-98297

A vulnerability exists in the Linux kernel Bluetooth hci_core component where functions hci_send_acl(), hci_send_sco(), and hci_send_iso() unconditionally queue hdev->tx_work. This creates a race condition during hci_dev_close_sync() while draining the hdev->workqueue (triggered by HCIDEVDO...

CVE-2026-98295

The Linux kernel contains a vulnerability in the Bluetooth subsystem related to coredump processing. The function hci_devcd_handle_pkt_init() incorrectly arms dump_timeout and coredump producers without holding an hdev reference . This allows these works to remain live during unregistration, pote...

CVE-2026-98294

The Linux kernel contains a vulnerability in the hci_qca driver where the system attempts to write to a serial port after it has been closed. Specifically, if HCI_QUIRK_NON_PERSISTENT_SETUP is set (e.g., for the WCN399x family), a failed hci_dev_open_sync() after a successful qca_setup() leads to...

CVE-2026-98293

The Linux kernel contains a memory leak vulnerability within the Bluetooth ISO component. Specifically, the iso_conn_ready() function fails to properly release a reference to the parent socket when iso_sock_alloc() fails. While the reference is normally dropped by sock_put() upon successful child...
