3DescriptionCVE.org
In kvm_iommu_map_sg of iommu.c, there is a possible use after free due to a missing permission check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Local privilege escalation in the Android kernel's KVM IOMMU subsystem allows a low-privileged user to gain full kernel control via a use-after-free condition in kvm_iommu_map_sg (iommu.c). The root cause is a missing permission check that enables memory to be accessed after it has been freed, allowing an unprivileged local process to achieve read/write/execute control over the kernel. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a local user-space process running with at least low privileges on an Android device that has the KVM IOMMU subsystem active - specifically devices using the Android Virtualization Framework or pKVM (protected KVM), which is present on Android 13+ devices with hardware virtualization support. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 7.8 (AV:L/AC:L/PR:L/UI:N) is well-calibrated for this class of vulnerability: local, low-complexity, low-privilege kernel UAF leading to full system compromise. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The upstream fix is available as kernel commit ad34d15396568919a8ddd306ce2120e76d111b7c on android.googlesource.com (https://android.googlesource.com/kernel/common/+/ad34d15396568919a8ddd306ce2120e76d111b7c). … Detailed patch versions, workarounds, and compensating controls in full report. |
