In Google Android, a critical vulnerability identified as CVE-2026-0106 has been discovered in the vpu_mmap function of vpu_ioctl. This vulnerability allows for an arbitrary address mmap due to a missing bounds check. The severity level of this vulnerability is classified as critical, with a CVSS score of 9.3, indicating a high level of risk for organizations using affected versions of the Android operating system.
Risk to organizations includes potential local privilege escalation with no additional execution privileges required. Notably, user interaction is not necessary for exploitation, making this vulnerability particularly concerning. The urgency for defenders is critical, and organizations should prioritize patching immediately.
As the vulnerability is currently unexploited and not present in the Known Exploited Vulnerabilities (KEV) catalog, there is still an opportunity for organizations to mitigate risks before potential exploitation occurs.
Organizations must take action promptly to ensure their systems remain secure and resilient against possible exploitation of this critical vulnerability.
Vulnerability Details
The CVE-2026-0106 vulnerability exists specifically within the vpu_mmap of vpu_ioctl in Android. The vulnerability type is classified as 'privilege escalation', which aligns with the risk of unauthorized elevation of privileges within the system. The CVSS 3.1 vector indicates that it has a local attack vector, low attack complexity, requires no privileges, and does not require user interaction. The impact on confidentiality, integrity, and availability is high.
This vulnerability was published on February 5, 2026, and has been classified under several CWEs, including CWE-119, CWE-125, and CWE-787, indicating various potential weaknesses related to memory management and bounds checking.
Technical Analysis
The root cause of CVE-2026-0106 stems from a missing bounds check within the vpu_mmap function of vpu_ioctl. This oversight allows an attacker with local access to potentially map arbitrary memory addresses, leading to a privilege escalation scenario. Consequently, the attacker can gain higher privileges than initially authorized, which can be detrimental depending on the system's security posture.
The attack vector is local, meaning that the attacker must have some level of access to the device. The attack complexity is categorized as low, indicating that an attacker could exploit this vulnerability with minimal effort. Importantly, no privileges are required to exploit this vulnerability, and user interaction is not needed, significantly increasing the risk.
In terms of impact, the vulnerability can compromise the confidentiality, integrity, and availability of affected systems, further underscoring its critical nature.
Risk & Impact Analysis
Organizations deploying Android systems face significant risks due to this vulnerability. The potential for local privilege escalation can lead to a complete compromise of the system's security, allowing attackers to bypass security controls and access sensitive data.
The blast radius of this vulnerability can be substantial, particularly in environments where multiple applications or services run under the same user context. Therefore, the urgency for remediation is critical. Organizations must act swiftly to patch their systems to prevent exploitation.
Given the CVSS score of 9.3, organizations should prioritize this vulnerability within their patch management cycles. The low likelihood of user interaction for exploitation should not lead to complacency; proactive measures are essential to maintain security hygiene.

Affected Versions
All versions of Google Android prior to the vendor patch are affected by this vulnerability. Organizations are advised to review their systems to ensure they are updated to the latest version.
Mitigation & Remediation
To mitigate the risk posed by CVE-2026-0106, organizations should apply the latest security patches provided by Google for the Android operating system. If immediate patching is not feasible, organizations should consider implementing workarounds such as restricting access to potentially vulnerable components and enhancing monitoring for unusual activity.
Organizations should also consider leveraging penetration testing to identify potential weaknesses and ensure that their security posture is robust against exploitation attempts.
Detection Guidance
Organizations should monitor logs for indicators of exploitation attempts, such as abnormal memory access patterns or unauthorized privilege changes. Behavioral anomalies, including unexpected application behavior or access requests, should also be investigated promptly. Network signatures related to unauthorized access attempts should be established to assist in identifying potential exploitation.
