Zephyr race condition vulnerability

Versions Zephyr 3.4.0 through 4.4.2 contain a race condition vulnerability. This issue arises because the Infineon PSOC 6 BLESS HCI driver stores HCI packet descriptors in shared file-scoped variables and fills those descriptors prior to acquiring signal quantities. As a result, multiple senders...

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

ROS-20260821-73-0031

The vulnerability of the Linux kernel Bluetooth HCI driver implementation relates to competitive access to resources during the execution of the sniffmin,maxintervalset function in the net/bluetooth/hcidebugfs.c module. Exploiting this vulnerability allows a remote attacker to compromise the...

ROS-20260821-73-0034

The vulnerability of the conninfomin,maxageset function in the net/bluetooth/hcidebugfs.c module. The implementation of the HCI driver in Linux operating systems is vulnerable due to integer overflow caused by concurrent access to resources race conditions. Exploiting this vulnerability could all...

CVE-2026-72454

A flaw was found in the Linux kernel's MIPI I3C Host Controller Interface HCI driver. A race condition in the i3chciaddrtodev function allows concurrent device addition or removal operations to modify a device list while it is being traversed without proper locking. This can lead to a...

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...
