> Hi Greg, thanks for your reply. Since there is no patch to fix CVE-2023-52624 in linux-5.10, there is a patch in the linux-6.7 branch, its commit is 2ef98c6d753a744e333b7e34b9cf687040fba57d ("drm/amd/display: Wake DMCUB before executing GPINT commands"). When we apply this patch to linux-5.10, there are lots of conflicts, and we found there are lots of dependent patches, and lots of patches are not proposed to fix the cve, they are presented to add new functions of the kernel.

This is not the correct way to submit patches for inclusion in the
stable kernel tree.  Please read:
    https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html
for how to do this properly.

Also, yes, we want to take the original commits, as you see on the
stable mailing list, submit a series of commits that are in Linus's tree
that resolve the issue (and send them to the proper people, as explained
in the link above.)

thanks,
