The BLUETOOTH trademarks are owned by Bluetooth SIG, Inc., U.S.A.\r\n\r\nSecurity Fix(es):\n\nBlueZ A2DP Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of BlueZ. An attacker must first obtain the ability to pair a malicious Bluetooth device with the target system in order to exploit this vulnerability.\n\nThe specific flaw exists within the handling of the stream endpoints. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-29429.(CVE-2026-19774)\n\nBlueZ 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)\n\nA 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)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"bluez","purl":"pkg:rpm/openEuler/bluez&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.71-7.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["bluez-5.71-7.oe2403sp3.aarch64.rpm","bluez-cups-5.71-7.oe2403sp3.aarch64.rpm","bluez-debuginfo-5.71-7.oe2403sp3.aarch64.rpm","bluez-debugsource-5.71-7.oe2403sp3.aarch64.rpm","bluez-devel-5.71-7.oe2403sp3.aarch64.rpm","bluez-libs-5.71-7.oe2403sp3.aarch64.rpm"],"noarch":["bluez-help-5.71-7.oe2403sp3.noarch.rpm"],"src":["bluez-5.71-7.oe2403sp3.src.rpm"],"x86_64":["bluez-5.71-7.oe2403sp3.x86_64.rpm","bluez-cups-5.71-7.oe2403sp3.x86_64.rpm","bluez-debuginfo-5.71-7.oe2403sp3.x86_64.rpm","bluez-debugsource-5.71-7.oe2403sp3.x86_64.rpm","bluez-devel-5.71-7.oe2403sp3.x86_64.rpm","bluez-libs-5.71-7.oe2403sp3.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3881"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-19774"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80185"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80186"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H"}],"database_specific":{"severity":"High"}}
