In smmu_install_nested_ste of arm-smmu-v3.c, there is a possible escalation of privilege due to a logic error in the code. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Local privilege escalation in the Android kernel's arm-smmu-v3 driver (smmu_install_nested_ste) lets a process that already runs with System execution privileges turn a logic error in SMMU stream-table-entry handling into full kernel-level compromise of confidentiality, integrity, and availability. Only devices whose kernel exposes the ARM SMMUv3 driver in a nested-translation configuration are affected, and Google rates it Moderate with a CVSS base of 6.7 (AV:L/PR:H), meaning exploitation presupposes a highly privileged local foothold rather than remote or unauthenticated access. …
