An update for bluez is now available for openEuler-24.03-LTS-SP4 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-3732 Final 1.0 1.0 2026-09-14 Initial 2026-09-14 2026-09-14 openEuler SA Tool V1.0 2026-09-14 bluez security update An update for bluez is now available for openEuler-24.03-LTS-SP4 This package provides all utilities for use in Bluetooth applications. The BLUETOOTH trademarks are owned by Bluetooth SIG, Inc., U.S.A. Security Fix(es): A vulnerability, which was classified as very critical, was found in Linux BlueZ (version now known).CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).This is going to have an impact on confidentiality, integrity, and availability.There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.(CVE-2026-19774) BlueZ sdp-xml.c type confusion via RegisterProfile(ServiceRecord) can crash bluetoothd (local DoS): a crafted nested ServiceRecord can corrupt the SDP XML parser stack so scalar union data is treated as a sequence pointer, allowing a local caller to crash bluetoothd.(CVE-2026-80185) A stack-based buffer overflow vulnerability exists in BlueZ, the Linux Bluetooth protocol stack. A remote user within Bluetooth radio range can send a specially crafted Extended Inquiry Response (EIR) packet that causes a buffer overflow when the target device performs Bluetooth discovery. This vulnerability can lead to a Denial of Service (DoS) by crashing the bluetoothd service and may allow for arbitrary code execution.(CVE-2026-80186) An update for bluez is now available for openEuler-24.03-LTS-SP4. openEuler Security has rated this update as having a security impact of high.
