Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: Fix handling of partial GPU mapping of BOs
This commit fixes the bug in the handling of partial mapping of the buffer objects to the GPU, which caused kernel warnings.
Panthor didn't correctly handle the case where the partial mapping spanned multiple scatterlists and the mapping offset didn't point to the 1st page of starting scatterlist. The offset variable was not cleared after reaching the starting scatterlist.
Following warning messages were seen.
