Cyber Security News ☛ SCAVY – Framework to Detect Memory Corruption in Linux Kernel for Privilege Escalation
Researchers have unveiled SCAVY, a novel framework designed to automate the discovery of memory corruption targets in the Linux kernel.
This discovery aims to address critical gaps in the detection and prevention of privilege escalation exploits, which often leverage memory-corruption vulnerabilities to gain unauthorized access to system resources.
Kernel privilege-escalation exploits typically exploit memory corruption vulnerabilities to overwrite specific memory locations, known as memory targets.

Fudzilla ☛ Boffins save 30 per cent on data centre power bills
Made some minor changes to Linux code
A team of boffins has emerged from their smoke-filled labs with a string of Linux code that they think can save 30 per cent on a data centre's power bill.
The University of Waterloo team in Canada, published on the Data Centre Dynamics website that the changes were made to the code that processes packets of network traffic.

TechSpot ☛ Researchers claim Linux kernel tweak could reduce data center energy use by 30%
Researchers have unveiled a small but powerful modification to the Linux kernel that could significantly reduce energy consumption in data centers. The proposed alteration comes at a crucial time, as computing currently accounts for about 5 percent of the world's daily energy use, with data centers being major contributors to this consumption.
Researchers at the University of Waterloo's Cheriton School of Computer Science, led by Professor Martin Karsten and including Peter Cai, identified inefficiencies in network traffic processing for communications-heavy server applications. Their solution, which involves rearranging operations within the Linux networking stack, has shown improvements in both performance and energy efficiency.
