The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - drm/nouveau: don't bump pin count on failed re-pin in nouveau_bo_pin_locked() nouveau_bo_pin_locked()     checks whether an already pinned BO is in a memory domain compatible with a new pin request. When the     domains are incompatible, it sets -EBUSY but still calls ttm_bo_pin() before returning. Callers treat a     failed nouveau_bo_pin() as not having acquired a new pin, so the extra pin count is never decreased by a     matching unpin. This triggers the warning in ttm_bo_release(): WARN_ON_ONCE(bo->pin_count); Found when     fuzzing the nouveau driver with a modified Syzkaller: WARNING: drivers/gpu/drm/ttm/ttm_bo.c:256 at     ttm_bo_release+0x827/0x9e0 drivers/gpu/drm/ttm/ttm_bo.c:256, CPU#1: syz.3.24/2212 Modules linked in: CPU:
