    It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB)
    invalidation before memory writes made through the invalidated translation were globally observed. A local
    attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing
    memory protections or escalating privileges. (CVE-2025-10263)
