Google, Intel Warn on 'Zero-Click' Kernel Bug in Linux-Based IoT Devices

Google and Intel are warning of a high-severity flaw in BlueZ, the Linux Bluetooth protocol stack that provides support for core Bluetooth layers and protocols to Linux-based internet of things IoT devices. Click to Register! According to Google, the vulnerability affects users of Linux kernel...

CVE-2020-15802

A flaw was found in the bluetooth specification that would allow an attacker within bluetooth radio range to abuse a protocol flaw which could allow key-overwrite in services. Mitigation As the bluetooth module will be auto-loaded when required, its use can be disabled by preventing the module fr...

CVE-2020-10135

A flaw was discovered in the Bluetooth protocol affecting the Bluetooth BR/EDR authentication. An attacker with physical access to the Bluetooth connection could perform a spoofing attack impersonating the address of a previously paired remote device. This attack may result in the attacking devic...

kernel: sensitive information disclosure from kernel stack memory via HIDPCONNADD command

A flaw was found in the Linux kernel's implementation of the Bluetooth Human Interface Device Protocol HIDP. A local attacker with access permissions to the Bluetooth device can issue an IOCTL which will trigger the dohidpsockioctl function in net/bluetooth/hidp/sock.c.c. This function can leak...
