Alpine Linux rebuilds GitLab after attempted RCE attack
Hackers attempted to exploit a critical GitLab vulnerability in Alpine Linux’s development infrastructure on October 20–21, prompting the open-source project to rebuild its GitLab server and reset all passwords over concerns of a possible compromise. The attacks targeted CVE-2026-97229, a maximum-severity remote code execution flaw, repeatedly crashing GitLab processes, with some attempts coming close to […]
Critical Linux kernel flaw allows remote root attacks on MPTCP servers
Security researchers at Anthropic have developed an exploit for a critical Linux kernel vulnerability that allows unauthenticated attackers to remotely execute commands as root on servers running Multipath TCP (MPTCP) listeners. The flaw, tracked as CVE-2026-98432, also affects ordinary TCP connections, although remote code execution has not been publicly demonstrated on servers without an MPTCP […]
CISA warns of Fragnesia Linux flaw chained in PHP2Shell attacks
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) warned federal agencies to patch a high-severity Linux kernel privilege escalation bug that attackers are chaining with the PHP2Shell flaws in the wild. Tracked as CVE-2026-46300 and known as Fragnesia, this vulnerability stems from a logic bug in the Linux XFRM ESP-in-TCP subsystem that lets attackers run malicious code with […]
Kali Linux 2026.3 released with 6 new tools, desktop updates
Kali Linux has released version 2026.3, its third release this year, featuring six new hacking tools, desktop environment improvements, refreshed build scripts, and more. This Linux distribution is available as an installable OS or as a live environment and supports a wide range of hardware, including Raspberry Pi devices and Android phones via Kali NetHunter. […]
Fake Arch Linux packages push malware with root privileges
A threat actor uploaded malicious packages to the Arch User Repository (AUR) that impersonated two popular helper tools, yay and paru. AUR is a community-maintained, widely-used package index for Arch Linux and derivative distributions that hosts package build scripts (PKGBUILDs) for third-party and proprietary tools, beta, or older package versions that are no longer available […]
New Spectre v2 attack variant leaks Linux root password hash in minutes
A new Spectre v2 attack variant called Branch Target Reuse (BTR) can recover root password hashes from Intel computers running Linux in just a few minutes. A BTR attack exploits stale information in a processor’s branch predictor after a just-in-time (JIT) engine reuses memory for new code. By manipulating this leftover information, an attacker can […]
CISA alerts of active exploitation of three Linux kernel flaws
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) is warning that hackers are exploiting three Linux kernel vulnerabilities, one of them rated critical. The three security issues were added separately last week and have severity ratings ranging from medium to critical. One of them, tracked as CVE-2025-39964, existed in the Linux kernel for 14 years. […]
Magento StyleSmuggler zero-day exploited to deploy Linux backdoor
A zero-day vulnerability dubbed “StyleSmuggler” affecting all versions of Magento and Adobe Commerce is being exploited in attacks to deploy a backdoor. The first exploitation incident was recorded on September 4 on a target running the latest security updates. E-commerce security company Sansec says that Adobe Enterprise Support confirmed earlier today that it was working […]
Mozilla updates GPG signing key for Firefox releases after exposure
Mozilla announced today that it updated the GPG key used to sign Firefox and Thunderbird releases after it was accidentally exposed on GitHub. However, in a Monday blog post, it noted that the risk of a supply chain attack in which threat actors could distribute malicious installers signed with the exposed key is low because only a […]
New TONTOU CPU attack bypasses Spectre v2 fixes, leaks Linux password hashes
Successfully exploiting the issue requires overcoming several obstacles, including redirecting kernel control flow, precisely aligning interrupts with the post-neutralization window, and using the interrupt handler to poison the branch predictor entry associated with the target indirect branch. The researchers address these challenges through installing ‘timers’ to trigger hardware interrupts, frequent injection of interrupts, and via […]
