In an example, a computing system includes electronic operations for detecting unauthorized attempts to access kernel virtual memory pages via trap entry detection, with operations including: generating a trap page with a physical memory address; assigning a phantom page at an open location in the privileged portion of the virtual memory address space; generating a plurality of phantom page table entries corresponding to an otherwise-unmapped privileged virtual memory region; placing the trap page in physical memory and placing the phantom page table entry in a page table map; and detecting an access to the trap page via the phantom page table entry, to trigger a response to a potential attack."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mitigating attacks on kernel address space layout randomization","description":"Various systems and methods for detecting and preventing side-channel attacks, including attacks aimed at discovering the location of KASLR-randomized privileged code sections in virtual memory addres","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10489308","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
