- 8Hacker News·9/25/2026securityAvast Antivirus Sandbox Escape Exploitation Detailed
This second part of the Avast research describes the full exploitation of CVE-2025-13032 on Windows 11. The writeup explains how a double-fetch bug in an Avast kernel driver was turned into a pool overflow, kernel read/write primitive, and SYSTEM-level privilege escalation.
- 4Hacker News·9/1/2026researchTurso Tests Readahead for io_uring Without Kernel Buffered I/O
A Hacker News post describes experiments adding readahead to Turso’s io_uring backend, which uses O_DIRECT and therefore cannot rely on kernel readahead. The measurements on a TPC-H workload show fewer device requests and better performance when application-level prefetching is enabled, largely because multiple reads can be in flight and merged by the kernel. The post also notes that btree-aware readahead could be more accurate than guessing from sequential file offsets.
