Service interruption via unchecked Non-Secure pointers
Published Sep 1, 2026 · Updated Sep 1, 2026
Untrusted pointer dereference in Samsung mTower before 06994e303637512e39062f3e037c222e8448e57e allows local users to interrupt service. The secure-world ioctl entry path accepts pointer-bearing buffers and memrefs from Non-Secure memory without validating their complete address ranges or snapshotting mutable parameters before dereference. Exploitation requires local code and user interaction, and the published consequence is interruption of the trusted execution environment rather than data disclosure or modification.
