Local Privilege Escalation
New CIFSwitch Linux flaw gives root on multiple distributions
A newly discovered local privilege escalation vulnerability dubbed ‘CIFSwitch’ in the Linux kernel could allow attackers to forge CIFS authentication key descriptions, abuse the kernel’s key request mechanism, and gain root privileges. The issue impacts multiple Linux distributions that ship vulnerable combinations of the kernel CIFS and cifs-utils (versions 6.14 and higher, although some older […]
Exploit released for new PinTheft Arch Linux root escalation flaw
A recently patched Linux privilege escalation vulnerability now has a publicly available proof-of-concept (PoC) exploit that allows local attackers to gain root privileges on Arch Linux systems. The vulnerability, named PinTheft by the V12 security team and still waiting to be assigned a CVE ID for easier tracking, exists in the Linux kernel’s RDS (Reliable […]
Exploit available for new DirtyDecrypt Linux root escalation flaw
A recently patched local privilege escalation vulnerability in the Linux kernel’s rxgk module now has a proof-of-concept exploit that allows attackers to gain root access on some Linux systems. Named DirtyDecrypt and also known as DirtyCBC, this security flaw was also autonomously found and reported by the V12 security team earlier this month, when the […]
New Fragnesia Linux flaw lets attackers gain root privileges
Linux distros are rolling out patches for a new high-severity kernel privilege escalation vulnerability that allows attackers to run malicious code as root. Known as Fragnasia and tracked as CVE-2026-46300, this security flaw stems from a logic bug in the Linux XFRM ESP-in-TCP subsystem that can enable unprivileged local attackers to gain root privileges by writing arbitrary bytes […]
Windows BitLocker zero-day gives access to protected drives, PoC released
A cybersecurity researcher has published proof-of-concept (PoC) exploits for two unpatched Microsoft Windows vulnerabilities named YellowKey and GreenPlasma, which are a BitLocker bypass and a privilege-escalation flaw. Known as Chaotic Eclipse or Nightmare Eclipse, the researcher describes the BitLocker bypass issue as functioning like a backdoor because the vulnerable component is present only in the […]
New Linux ‘Dirty Frag’ zero-day gives root on all major distros
A new Linux zero-day exploit, named Dirty Frag, allows local attackers to gain root privileges on most major Linux distributions with a single command. Security researcher Hyunwoo Kim, who disclosed it earlier today and published a proof-of-concept (PoC) exploit, says this local privilege escalation was introduced roughly nine years ago in the Linux kernel’s algif_aead cryptographic algorithm interface. Dirty […]
New Linux ‘Copy Fail’ flaw gives hackers root on major distros
An exploit has been published for a local privilege escalation vulnerability dubbed “Copy Fail” that impacts Linux kernels released since 2017, allowing an unprivileged local attacker to gain root permissions. The vulnerability is tracked as CVE-2026-31431 and was discovered by the offensive security company Theori, using its AI-driven pentesting platform Xint Code after scaning the […]
Recently leaked Windows zero-days now exploited in attacks
Threat actors are exploiting three recently disclosed Windows security vulnerabilities in attacks aimed at gaining SYSTEM or elevated administrator permissions. Since the start of the month, a security researcher known as “Chaotic Eclipse” or “Nightmare-Eclipse” has published proof-of-concept exploit code for all three security issues in protest to how Microsoft’s Security Response Center (MSRC) handled […]
Disgruntled researcher leaks “BlueHammer” Windows zero-day exploit
Exploit code has been released for an unpatched Windows privilege escalation flaw reported privately to Microsoft, allowing attackers to gain SYSTEM or elevated administrator permissions. Dubbed BlueHammer, the vulnerability was published by a security researcher discontent with how Microsoft’s Security Response Center (MSRC) handled the disclosure process. Since, the security issue has no official patch and there […]
CISA: High-severity Linux flaw now exploited by ransomware gangs
CISA confirmed on Thursday that a high-severity privilege escalation flaw in the Linux kernel is now being exploited in ransomware attacks. While the vulnerability (tracked as CVE-2024-1086) was disclosed on January 31, 2024, as a use-after-free weakness in the netfilter: nf_tables kernel component and was fixed via a commit submitted in January 2024, it was first introduced […]
