UnverifiedAs long as any process holds a reference to a socket file descriptor, the corresponding socket will not be reclaimed by the kernel—this is the underlying mechanism by which port leaks can survive across processes.70% similarUnverifiedIn the Linux kernel, each network socket is represented as a file descriptor; when a process forks a child process, the child inherits the parent's file descriptor table via a reference-counting mechanism, causing port leaks to survive across processes.65% similarVerifiedSandbox technology confines the execution of untrusted code to a controlled environment through means such as process isolation, file system isolation, and network isolation.60% similarUnverifiedModifying the Bundle ID may invalidate the code signature, which can then be blocked by the system's Gatekeeper.55% similar
