Description OSIDB Bzimport 2026-10-23 12:05:06 UTC 
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.
