  Confirmed
Status in linux-oem-5.10 source package in Focal:
  Fix Released

Bug description:
  
      SRU Justification

      Impact:
         The upstream process for stable tree updates is quite similar
         in scope to the Ubuntu SRU process, e.g., each patch has to
         demonstrably fix a bug, and each patch is vetted by upstream
         by originating either directly from a mainline/stable Linux tree or
         a minimally backported form of that patch. The following upstream
         stable patches should be included in the Ubuntu kernel:

         5.10.52 upstream stable release
         from git://git.kernel.org/
