Details

In the Linux kernel, the following vulnerability has been resolved:

drm/nouveau/gsp: add SEC2 to GA100 chip table

The booter-load and booter-unload firmware run on the SEC2 falcon. During tu102_gsp_oneinit(), the booter constructor needs device->sec2 to access the SEC2 falcon.

Without the .sec2 entry, device->sec2 is NULL and this dereference crashes during GSP-RM boot.
