Arbitrary memory access via missing range checks
Published Mar 24, 2020 · Updated Aug 4, 2024
Out-of-bounds access in Samsung Exynos Android 8.x through 10.0 allows remote attackers to read and write memory through the Widevine Trustlet. Missing address-access checks let the trustlet accept non-secure memory locations outside its permitted range for both read and write operations. Exploitation requires an affected Exynos device; Samsung has not published the request path, and confirmed impact is non-secure-memory disclosure and modification.
