• Updated /tmp/hacktricks_update_gbs3tyew/repo/src/binary-exploitation/rop-return-oriented-programing/ret2esp-ret2reg.md with:

  • a modern CET-IBT note explaining why opcode-only ff e4 / ff d4 hits are weaker on hardened x86 targets because indirect targets must land on ENDBR32/ENDBR64;
  • an ARM64 BTI-aware ret2reg note (br xN vs blr xN landing pads) plus a readelf -n check for AArch64 feature: BTI, PAC;
  • a quick readelf / objdump triage snippet in Protections; and
  • a small structure fix so ## References is the last heading in the file. (docs.kernel.org)

• Validation:

  • no forbidden sources were introduced;
  • git diff --check is clean;
  • mdbook build could not be run here because mdbook is not installed.
