Description

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) is warning that hackers are exploiting vulnerabilities in the Linux kernel and Android operating system. [...]

Impact

Successful exploitation of CVE-2025-48595 can lead to privilege escalation on affected Android devices without user interaction, potentially allowing attackers to gain elevated privileges. CVE-2022-0492 enables local attackers to bypass container isolation and escalate privileges to root on the host system, particularly impacting containerized environments using cgroups v1 with elevated capabilities. These impacts pose significant risks to system integrity and security, especially in environments relying on containerization and Android devices running vulnerable versions.

Defensive guidance

For CVE-2025-48595, apply the June 2026 Android security patches (2026-06-01 and 2026-06-05 security patch levels) provided by Google. For CVE-2022-0492, upgrade Linux kernels to versions 4.9.301 or later, 4.14.266 or later, 4.19.229 or later, 5.4.177 or later, 5.10.97 or later, 5.15.20 or later, 5.16.6 or later, or 5.17-rc3 or later as appropriate. Federal agencies must comply with CISA's BOD 22-01 directive to patch or discontinue use of affected software by June 5, 2026. Organizations should prioritize patching these vulnerabilities promptly. No additional vendor advisories indicate that no action is required or that these issues are mitigated by other means.

Summary

This threat involves two actively exploited vulnerabilities identified by CISA. CVE-2025-48595 is an integer overflow in the Android Framework affecting Android 14 to 16, exploitable without user interaction for privilege escalation. Google released patches in June 2026 to remediate this issue. CVE-2022-0492 is a privilege escalation vulnerability in the Linux kernel's cgroup_release_agent_write() function within the cgroups v1 subsystem. It allows local attackers to bypass namespace isolation and escape containers, gaining root privileges on the host. This flaw affects multiple Linux kernel branches from 2.6 through 4.20 and 5.5 through 5.17 and is fixed in kernel versions 4.9.301+, 4.14.266+, 4.19.229+, 5.4.177+, 5.10.97+, 5.15.20+, 5.16.6+, and 5.17-rc3+. Both vulnerabilities are listed in CISA's KEV catalog, triggering mandatory remediation for federal agencies under BOD 22-01.
