In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: Fixed an issue involving a use-after-free in hcisendacl. This fix addresses the issue caused by receiving HCIEVDISCONNPHYLINKCOMPLETE, which does not call hciconndel without first checking whether conn-type is...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: In hcievent, there is a callback for call disconnect that is called before the connection is deleted. In hcicsdisconnect, we call hciconndel even if the disconnection fails. ISO, L2CAP, and SCO connections refer to...

CVE-2026-18411 Use of hard-coded cryptographic key in Acrisure KARR BT and DR-100

The KARR Security System and SWDS dealer-installed automotive anti-theft systems use a shared Bluetooth authentication key across affected devices.
