CVE-2026-25205

Memory corruption via unchecked code-cache string length

Published Apr 13, 2026 · Updated Apr 13, 2026

Heap-based buffer overflow in Escargot at commit 97e8115ab1110bc502b4b5e4a0c689a71520d335 allows local users to overwrite heap memory. CodeCacheReader::loadStringTable allocates buffers from a declared maximum length, then copies cache-supplied string lengths without verifying that they fit. Exploitation requires a crafted local code-cache file and can corrupt process memory, causing a crash or enabling control of the affected process.
