Public bug reported:
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: upstream stable patchset 2025-03-13 Ported from the following upstream stable releases: v6.6.67, v6.12.6 from
