CVE-2026-65330 is a kernel memory-handling vulnerability in Apple operating systems. A locally executing application may trigger unexpected system termination or corrupt kernel memory. Apple addressed the issue through improved memory handling. The specific vulnerable kernel function and underlying memory-safety weakness were not disclosed.

The repository contains a short README and one standalone Perl proof of concept, necp_trie_uaf_poc_platform.pl. It targets CVE-2026-65330, an alleged local use-after-free in Apple XNU's NECP domain-trie handling. The script directly invokes NECP session syscalls (SYS_necp_session_open 522 and SYS_necp_session_action 523), rather than using network traffic or a remote service. It constructs a minimal serialized domain trie, creates two tries in one NECP session, closes that session without removing the tries, and treats the remaining ownership linkage as dangling. It then opens many additional sessions and adds tries to heap-spray/reclaim the freed session memory. A separate session removes the orphaned trie, aiming to corrupt a sprayed session's owner list, after which REMOVE_ALL_DOMAIN_TRIES operations traverse the corrupted lists and may panic the kernel. A final trie removal attempts to force another global/list traversal. Options provide configurable spray volume (1-4096, default 200), debug output, and a non-destructive --smoke mode that only verifies session creation, trie addition, and remove-all behavior. The code is a kernel-crash/UAF validation PoC with no post-exploitation payload or remote endpoint.
