CVE-2026-11894

The Realtek BEE Bluetooth HCI driver's send callback, bthcibeesend in drivers/bluetooth/hci/hcibee.c, violated the bthcidriverapi buffer-ownership contract. That contract requires the driver to consume unref the transmit netbuf only on success; on an error return the host caller retains ownership...

CVE-2026-11893

The Bluetooth HCI driver for Bouffalo Lab on-chip BLE controllers BL60x/BL70x/BL61x, btbflbsend in drivers/bluetooth/hci/hcibflb.c, violates the bthcidriverapi.send buffer-ownership contract. That contract documented at include/zephyr/drivers/bluetooth.h requires the buffer reference to be consum...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: i3c: mipi-i3c-hci: Fixed out-of-bounds access in hcidmairqhandler. Do not loop over ring headers in hcidmairqhandler, which are not allocated and enabled in hcidmainit. Otherwise, out-of-bounds access will occur when accessing...

Linux kernel null pointer dereference vulnerability (CNVD-2025-04161)

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. Linux kernel suffers from a NULL pointer dereference vulnerability, which originates from the mipi-i3c-hci driver stopping the ring without first masking the ring interrupt,...

The vulnerability of the {conn,adv}_{min,max}_interval_set() function in the implementation of the HCI driver for Bluetooth in Linux operating systems allows a attacker to compromise the integrity of protected information and cause service failure.

The vulnerability of the conn,advmin,maxintervalset function in the implementation of the HCI driver for Bluetooth in Linux operating systems is related to competitive access to resources race conditions. Exploiting this vulnerability can allow a malicious actor to cause service failures remotely...
