LegionCbmrFix 1.0.0

1.0.0 · 2026-10-17

First release. Fixes vm_page_validate_no_references kernel panics on the Lenovo Legion 5 15IAX10 (BIOS S2CN26WW) by unloading Microsoft's cbmr_driver.efi from the firmware before macOS boots and reserving its 164 KiB at 0x180000000.

Tested with OpenCore 1.0.8 on macOS 15.8.1 (24H32) and 26.7.1 (25G241). Install: copy LegionCbmrFix.efi to EFI/OC/Drivers and add it to UEFI > Drivers, then check with tools/cbmr-status.sh (see the README).

SHA-256 of LegionCbmrFix.efi: 13cb762ed028f5326cecb57a61c7496e90fb3d44fdbeea5c4e978ca8a9cfe4e9 (built with LLVM 20, same as a local ./build.sh).
