In January 2024, CVE-2024-21626 showed that a file descriptor leak in runc (the standard container runtime) allowed containers to access the host filesystem. The container’s mount namespace was intact — the escape happened through a leaked fd that runc failed to close before handing control to the container. In 2025, three more runc CVEs (CVE-2025-31133, CVE-2025-52565, CVE-2025-52881) demonstrated mount race conditions that allowed writing to protected host paths from inside containers.
The tradeoff is complexity. The microcode must be carefully arranged so that the instructions in delay slots are either useful setup for both paths, or at least harmless if the redirect fires. Not every case is as clean as RETF. When a PLA redirect interrupts an LCALL, the return address is already pushed onto the microcode call stack (yes, the 386 has a microcode call stack) -- the redirected code must account for this stale entry. When multiple protection tests overlap, or when a redirect fires during a delay slot of another jump, the control flow becomes hard to reason about. During the FPGA core implementation, protection delay slot interactions were consistently the most difficult bugs to track down.。爱思助手下载最新版本对此有专业解读
