Executive Summary
In June 2026, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) added two critical vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog: CVE-2025-48595 and CVE-2022-0492. CVE-2025-48595 is a high-severity integer overflow vulnerability in the Android Framework affecting versions 14 through 16, allowing local privilege escalation without user interaction. CVE-2022-0492 is a privilege escalation flaw in the Linux kernel's cgroups v1 subsystem, enabling attackers to bypass namespace isolation and potentially gain root access on host systems. Both vulnerabilities have been actively exploited in the wild, prompting immediate patching and mitigation efforts.
The inclusion of these vulnerabilities in the KEV catalog underscores the persistent threat posed by privilege escalation flaws in widely used operating systems. Organizations are urged to prioritize the application of security updates to mitigate potential exploitation risks and protect their systems from unauthorized access and control.
Why This Matters Now
The active exploitation of these vulnerabilities highlights the urgency for organizations to apply security patches promptly to prevent potential breaches and maintain system integrity.
Attack Path Analysis
Attackers exploited vulnerabilities in Android and Linux systems to gain initial access and escalate privileges. They then moved laterally within the network, established command and control channels, exfiltrated sensitive data, and caused significant impact.
