This is a well-structured 11-patch series that hardens the nova-core VBIOS parsing code against malformed firmware. The first 5 patches fix real bugs (integer overflows, unchecked array accesses on firmware-derived values), properly tagged with `Fixes:` lines. Patches 6-10 are incremental refactoring that removes the `FwSecBiosBuilder` intermediate struct, simplifying the code substantially (net -50 lines). Patch 11 aligns PCI-AT/FWSEC image selection with nouveau behavior.
The series is logically ordered, each patch compiles independently, and the refactoring is well-motivated. The Rust idioms used (`.get()`, `.checked_add()`, `.checked_sub()`, `.and_then()`, `.ok_or()`) are appropriate for hardening firmware-derived data paths. Joel Fernandes has reviewed most patches.
I have one substantive concern (unchecked subtraction in patch 9) and a few minor observations.
