FIRM Sysmodules

FIRM sysmodules were updated. Specific diffs for a few sysmodules are below <check back later, to be updated>:

Loader
  • ldr:pm->CreateProcess() now performs additional validation on the NPDM header.
    • When the title id is one of certain hardcoded titles, Loader now validates that the version field at NPDM header is non-zero. This prevents selectively downgrading those titles to versions vulnerable to known exploits.
    • The titles checked are:
      • settings
      • bus
      • audio
      • nvservices
      • ns
      • ssl
      • es
      • creport
      • ro
