Memory corruption in GLib's memory management functions, leading to SIGSEGV in g_slice_free_chain_with_offset. NULL pointer dereference in __strchr_avx2 when the name parameter becomes NULL. System resource corruption detected by memory protections, leading to abort() calls. This vulnerability is particularly concerning in automotive environments (IVI systems) where ConnMan is commonly deployed, as abnormal termination of DNS processes can significantly impact overall system safety and stability.
