In smmu_detach_dev_nested of arm-smmu-v3.c, there is a possible escalation of privilege due to improper input validation. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Local escalation of privilege in the Android kernel's ARM SMMU v3 driver lets a process that already runs with System privileges reach kernel-level code execution by passing malformed input to the nested device-detach path (smmu_detach_dev_nested in arm-smmu-v3.c). Because the CVSS vector requires PR:H, this is not a boundary an ordinary unprivileged app can cross — it is a second-stage escalation for code that already holds highly privileged, kernel-adjacent access on the device. …
