Kernel Privilege Escalation Has One Linux Maintainer Contemplating a 'Kill Switch'Back-to-back kernel vulnerabilities in Linux has defenders scrambling to apply defenses in the age of quick turnaround time for hackers to exploit nascent flaws. "Dirty Frag" and "Copy Fail" kernel privilege escalation vulnerabilities became public knowledge within two weeks of each other.

No Patches Yet Available, After Third Party Published Vulnerability DetailsSecurity researchers have discovered a new, critical flaw in the Linux kernel that attackers can exploit to gain root access. No patches are yet available to fix "Dirty Frag," the second new local privilege escalation flaw to be found in two weeks, following the similar "Copy Fail" vulnerability.

AI-Assisted Offensive Security Researcher Discovered Flaw After 1 Hour of ScanningPatch all Linux kernels issued from 2017 onwards to fix a serious vulnerability in the kernel’s cryptography API that can be easily exploited by a local, unprivileged user to gain root-level access. The major flaw is the latest to be found by an AI-assisted researcher.

Race-Condition Bugs in Ubuntu and Red Hat Tools Could Leak Sensitive Memory DataHackers could exploit a tool that stores crashed system data in older Linux operating systems to obtain passwords and encryption keys, warn researchers. The flaw lies in the way certain Linux distributions, including Ubuntu, Red Hat, and Fedora, handle application crashes.

Vulnerability Researchers: Start Tracking LLM Capabilities, Says Veteran Bug HunterLarge language models have taken a big step forward in their ability to help chase down code flaws, said a vulnerability researcher who successfully trained OpenAI's o3 to review Linux kernel code, leading to the LLM - in an apparent first - discovering a new zero-day vulnerability in the code.

Attackers Can Employ a Vulnerable Driver to Target Most Windows and Linux SystemsResearchers are warning Microsoft Windows as well as many Linux distribution users to install updates that revoke permissions for a vulnerable driver that attackers can use to target most systems, allowing them to bypass UEFI Secure Boot and install a bootkit to take full control of a system.

Embedded Device Operating Sytem Had Flaw Allowing Hacers to Bypass Integrity CheckA critical flaw in the updating service of a popular Linux operating system for embedded devices could enable hackers to compromise firmware with malicious images. OpenWrt developers patched the vulnerability, with a CVSS core of 9.3 and tracked as CVE-2024-54143.

Exploitation Requires Victim to Print On Rogue PrinterAttackers can exploit a series of vulnerabilities in the OpenPrinting Common Unix Printing System utility to remotely execute arbitrary code on certain machines. Major Linux distributions reacted Friday by releasing patches. Exploitation requires a victim to attempt to print from a malicious device.
