CVE-2026-25207

Memory corruption via unchecked code-cache lengths

Published Apr 13, 2026 · Updated Apr 13, 2026

An out-of-bounds write in Samsung Escargot allows local users to corrupt memory through crafted code-cache data. CodeCacheReader::loadStringTable trusts serialized length values that can exceed the allocated maximum string length, then copies that length into the undersized buffer and writes a terminator beyond it. The issue requires local access and high-complexity cache manipulation; Samsung identifies only commit 97e8115ab1110bc502b4b5e4a0c689a71520d335 as affected, and successful triggering can compromise confidentiality, integrity, and availability.
