Firmware Vulnerabilities affecting Dell Laptops Could allow attackers to achieve persistent access 

A set of vulnerabilities affecting millions of Dell laptops used by government agencies, cybersecurity professionals, and enterprises worldwide. The vulnerability known as “ReVault,” mainly target the Broadcom BCM5820X security chip embedded in Dell’s ControlVault3 firmware.

This subsequently create opportunities for attackers to steal passwords, biometric data, and maintain persistent access to compromised systems.

How does the vulnerability work

Most of the flaws reside in the firmware for ControlVault3 and ControlVault3+, which are hardware security components that store passwords, biometric templates, and security codes.

The lists includes:

  • Two out-of-bounds vulnerabilities (CVE-2025-24311, CVE-2025-25050)
  • An arbitrary free (CVE-2025-25215) flaw
  • A stack-overflow bug (CVE-2025-24922)
  • An unsafe-deserialization flaw (CVE-2025-24919)

According to the researchers, the vulnerabilities can be exploited in so-called ReVault attacks by:

  • Attackers who have achieved non-administrative access/privileges on a vulnerable target laptop. The vulnerabilities may allow them to interact with the ControlVault firmware and leak key material that would allow them to permanently modify the firmware (i.e., effectively creating a potential backdoor into the system)
  • Attackers that have physical access to the laptop. They could pry the device open, use a custom connector to access the Unified Security Hub board (which runs ControlVault) over USB, and exploit those vulnerabilities – all without having to log into the system beforehand or having knowledge of the full-disk encryption password.

“Another interesting consequence of this scenario is that if a system is configured to be unlocked with the user’s fingerprint, it is also possible to tamper with the CV firmware to accept any fingerprint,” as per researchers.

Technical details have not been publicly shared, but they have, of course, been privately reported to Dell and Broadcom.

These are 5 critical vulnerabilities of ReVault found by Cisco Talos researcher

ReVault Attack – Five Critical Vulnerabilities

ControlVault3 and ControlVault3+ systems:

  • CVE-2025-24311: An out-of-bounds read vulnerability that enables information leakage
  • CVE-2025-25050: An out-of-bounds write flaw allowing code execution
  • CVE-2025-25215: An arbitrary memory free vulnerability
  • CVE-2025-24922: A stack-based buffer overflow enabling arbitrary code execution
  • CVE-2025-24919: An unsafe deserialization flaw in ControlVault’s Windows APIs

Importance of device security posture/Endpoint security

The incident highlight how device posture check is designed to evaluate threat that a device poses to an organization and its systems.

The persistent nature of these attacks represents a significant escalation in firmware-based threats, as the malicious code resides below the operating system level.

Here traditional antivirus solutions cannot detect or remove it. Now sophistication of cyber threats means that organizations need to become more proactive in terms of defense.

The identification and mitigation of a threat early on, via an effective and clearly defined security posture, reduces costs, lessens downtime, and minimizes reputational damage.

Periodic security audits are essential to have a complete check on all the security features of the organization. Such audits identify vulnerabilities in the current security controls and allow for ensuring things align properly with industry standards. 

Importance of Endpoint security

End point security detect and prevent security threats like file-based malware attacks among other malicious activities. It also provides investigation and remediation capabilities needed to respond to dynamic security incidents and alerts.

Conclusion:

Protecting against endpoint attacks is challenging for organisation because endpoints exist where humans and machines intersect. With the increasing number of adversaries trying to breach organizations using sophisticated cyberattacks, quickly detecting potential threats will help speed the remediation process and keep data protected.

Linux Local Privilege Escalation via udisksd and libblockdev (CVE-2025-6019) PoC released 

Summary : A local privilege escalation vulnerability poc has been released, tracked as CVE-2025-6019, discovered in the udisksd daemon and its backend libblockdev library, affecting widely used Linux distributions including Fedora and SUSE.

Severity High 
CVSS Score 7.0 
CVEs CVE-2025-6019 
POC Available Yes 
Actively Exploited No 
Exploited in Wild No 
Advisory Version 1.0 

Overview 

CVE-2025-6019 is a local privilege escalation (LPE) vulnerability affecting systems where: 

  • udisksd is installed and running (e.g., Fedora, SUSE) 
  • Users in the allow active group are trusted to execute disk-related actions 
  • libblockdev fails to validate privileged backend operations under unprivileged contexts 

This flaw allows unprivileged users in the “allow_active” group to escalate privileges and execute commands as root by exploiting insecure trust boundaries in D-Bus IPC communication. 

Vulnerability Name CVE ID Product Affected Severity 
​Local Privilege Escalation Vulnerability  CVE-2025-6019 udisksd / libblockdev  High 

Technical Summary 

This vulnerability is triggered when an attacker in the “allow_active” group issues a crafted D-Bus request to the udisksd daemon using tools like udisksctl. Because the daemon improperly relies on group membership alone (without UID validation), it mistakenly grants root-level mount permissions. 

An attacker can exploit this by  

  • Crafting a malicious disk image (like XFS with a SUID-root shell). 
  • Using “udisksctl mount -b /dev/loop0” to mount it as root. 
  • Escalating privileges and compromising the system. 
CVE ID System Affected  Vulnerability Details Impact 
CVE-2025-6019 Fedora, SUSE, and other Linux distros using udisks2/libblockdev Improper user validation in D-Bus authorization allows unprivileged users to perform privileged disk operations.  Local privilege escalation to root 

Remediation: 

Here are the recommendations below 

  • Update “udisks2” and “libblockdev” to the latest versions provided by your distribution. 
  • Audit and restrict membership of the “allow_active” group. 
  • Disable unsafe or legacy D-Bus actions in system services where possible. 

Conclusion: 
CVE-2025-6019 highlights a breakdown in privilege boundary enforcement within a core system component used by many Linux desktop environments.

The availability of a public PoC, combined with the low complexity of exploitation, makes this vulnerability highly dangerous, particularly in multi-user or shared computing environments. 

Organizations must act swiftly to patch vulnerable systems, reassess group-based privilege models and implement stricter D-Bus and Polkit rules to reduce attack surface.
