CVE-2026-4010Public exploit

Compiler crash via underflowed error-string length

Published Mar 12, 2026 · Updated Mar 12, 2026

Memory corruption in pocketlang cc73ca61b113d48ee130d837a7a8b145e41de5ce allows local users to crash the compiler with a malformed script. An unterminated string drives an integer-underflowed length of 4294967290 into pkByteBufferAddString, whose copy loop reads past the source buffer. Exploitation requires local execution of the crafted script and causes a segmentation fault during compile-time error reporting, interrupting the process.
