Summary from the TLDR InfoSec newsletter

AI tools helped a security researcher track down a serious memory bug in a Windows file system driver. By comparing an old and a new version of the driver, the author identified a risky change and then used timing tricks to trigger a bug in which freed memory is reused. Connected to Ghidra, LLMs explained confusing functions, named important structures, and highlighted where the bug lived, so the researcher could focus on logic instead of wading through code.
