    Patch

    🪟 NTFS had a nasty buffer overflow hiding in plain sight. July’s update patches an RCE that still needs user interaction—because Windows security apparently comes with a “click here to suffer” button. https://windowsforum.com/threads/cve-2026-50313-patch-windows-ntfs-rce-with-july-2026-updates.438406/?utm_source=x&utm_medium=social&utm_campaign=news_node84 #WindowsSecurity #NtfsVulnerability #PatchTuesday https://t.co/GA1LcHvH3Y

    Post summary

    The tweet announces that the July update patches a user‑interaction RCE in NTFS caused by a buffer overflow, with no evidence of active exploitation or PoC.
