A 16-year-old Linux kernel vulnerability, dubbed Januscape, allows attackers to escape a virtual machine and execute arbitrary code on the host. [...]
Januscape: A 16-year-old Linux KVM flaw lets cloud VM tenants crash hosts and potentially escape guests. It affects Intel and AMD systems. Security researcher Hyunwoo Kim has published details of a use-after-free vulnerability in Linux’s KVM hypervisor that allows code running inside a guest virtual machine to corrupt host kernel memory. The bug, tracked as […]
A use-after-free bug in Linux's KVM hypervisor can be triggered from a guest virtual machine to corrupt the shadow-page state of the host kernel that runs it
The security vulnerability known as React2Shell is being exploited by threat actors to deliver malware families like KSwapDoor and ZnDoor, according to findings from Palo Alto Networks Unit 42 and NTT Security
Cybersecurity researchers have discovered two new malware families, including a modular Apple macOS backdoor called CHILLYHELL and a Go-based remote access trojan (RAT) named ZynorRAT that can target both Windows and Linux systems
The Clear Linux OS team has announced the shutdown of the project, marking the end of its 10-year existence in the open-source ecosystem. [...]
The latest generations of Intel processors, including Xeon chips, and AMD's older Zen 1, Zen 1+, and Zen 2 microarchitectures on Linux are vulnerable to new speculative execution attacks that bypass existing 'Spectre' mitigations. [...]
Researchers have demonstrated the "first native Spectre v2 exploit" for a new speculative execution side-channel flaw that impacts Linux systems running on many modern Intel processors. [...]
Cybersecurity researchers have disclosed what they say is the "first native Spectre v2 exploit" against the Linux kernel on Intel systems that could be exploited to read sensitive data from the memory
Linux users have reported seeing weird white flashes and rapid blinking on their Intel laptop displays after upgrading to Linux kernel version 5.19.12, leading to warnings that the bug may damage displays. [...]
