Researchers discovered two local privilege escalation flaws that could let attackers gain root access on systems running major Linux distributions. Qualys researchers discovered two local privilege escalation (LPE) vulnerabilities, an attacker can exploit them to gain root privileges on machines running major Linux distributions. The two vulnerabilities are: The first flaw (CVE-2025-6018) allows an unprivileged […]

The vulnerability, CVE-2023-0386 (CVSS score: 7.8), is an improper ownership vulnerability in the Linux kernel that […]
Qualys warns of two information disclosure flaws in apport and systemd-coredump, the core dump handlers in Ubuntu, Red Hat Enterprise Linux, and Fedora distros. Researchers discovered a vulnerability in Apport (Ubuntu’s core dump handler) and another bug in systemd-coredump, which is used in the default configuration of Red Hat Enterprise Linux 9 and the Fedora distribution. systemd-coredump automatically captures “core […]
Researchers created a PoC rootkit called Curing that uses Linux’s io_uring feature to evade traditional system call monitoring. Armo researchers have demonstrated a proof-of-concept (PoC) rootkit named Curing that relies on Linux asynchronous I/O mechanism io_uring to bypass traditional system call monitoring. “Curing is a POC of a rootkit that uses io_uring to perform different tasks without using any syscalls, […]
U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Linux Kernel flaws to its Known Exploited Vulnerabilities catalog. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added Linux Kernel flaws, respectively tracked as CVE-2024-53197 and CVE-2024-53150, to its Known Exploited Vulnerabilities (KEV) catalog. The vulnerability CVE-2024-53197 (CVSS score of 7.8) resides in the Linux kernel’s ALSA USB-audio driver affecting Extigy […]
A researcher released a free decryptor for Linux Akira ransomware, using GPU power to recover keys through brute force. Security researcher Yohanes Nugroho created a free decryptor for Linux Akira ransomware, using GPUs to brute force the decryption keys. Initially estimating a week, the project took three weeks and cost $1,200 in GPU resources due […]
U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Linux kernel vulnerability to its Known Exploited Vulnerabilities catalog. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added a Linux kernel vulnerability, tracked as CVE-2024-53104, to its Known Exploited Vulnerabilities (KEV) catalog. The February 2025 Android security updates addressed 48 vulnerabilities, the zero-day flaw CVE-2024-53104 which is actively exploited in attacks […]
The ‘Bootkitty’ Linux UEFI bootkit exploits the LogoFAIL flaws (CVE-2023-40238) to target systems using vulnerable firmware. Cybersecurity researchers from ESET recently discovered the first UEFI bootkit designed to target Linux systems, called by its authors Bootkitty. The bootkit allows attackers to disable the kernel’s signature verification feature and to preload two as yet unknown ELF […]
ESET discovered the first Unified Extensible Firmware Interface (UEFI) bootkit specifically designed for Linux systems, named Bootkitty. Cybersecurity researchers from ESET discovered the first UEFI bootkit designed to target Linux systems, called by its authors Bootkitty. The bootkit allows attackers to disable the kernel’s signature verification feature and to preload two as yet unknown ELF […]
China-linked APT Gelsemium has been observed using a new Linux backdoor dubbed WolfsBane in attacks targeting East and Southeast Asia. China-linked APT Gelsemium has deployed a previously unknown Linux backdoor, WolfsBane, in attacks targeting East and Southeast Asia, according to ESET. Victims include entities in Taiwan, the Philippines, and Singapore, as seen in VirusTotal samples from […]
