Linux Kernel Bug Opens Door to Wider Cyberattacks

The information-disclosure flaw allows KASLR bypass and the discovery of additional, unpatched vulnerabilities in ARM devices.
An information-disclosure security vulnerability has been discovered in the Linux kernel, which can be exploited to expose information in the kernel stack memory of vulnerable devices.
Specifically, the bug (CVE-2020-28588) exists in the /proc/pid/syscall functionality of 32-bit ARM devices running Linux, according to Cisco Talos, which discovered the vulnerability. It arises from an improper conversion of numeric values when reading the file.

BleedingTooth: Linux Bluetooth Zero-Click Remote Code Execution

Introduction
I noticed that the network subsystem was already being fuzzed extensively by syzkaller, but that subsystems like Bluetooth were less well covered. In general, research on the Bluetooth host attack surface seemed to be quite limited – with most public vulnerabilities in Bluetooth only affecting the firmware or the specification itself, and only allowing attackers to eavesdrop and/or manipulate information.
But what if attackers could take full control over devices? The most prominent examples that demonstrated this scenario were BlueBorne and BlueFrag. I set myself the goal to research the Linux Bluetooth stack, to extend upon BlueBorne’s findings, and to extend syzkaller with the capability to fuzz the ....
