Including patch for CVE-2020-25705 into upcoming Core Update 153?

Including patch for CVE-2020-25705 into upcoming Core Update 153?

Hello *,

since Core Update 153 is already scheduled to come with a new kernel, including this
patch against CVE-2020-25705 (dubbed "SADDNS" at the time of writing) into it makes
sense IMHO:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b38e7819cae946e2edf869e604af1e65a5d241c5

Further reading is available at, for example, ZDNet:

Thanks, and best regards,
Peter Müller

Hello,

Yes, we should add this patch to the currently open next branch.

Who will send a patch?

Best,
-Michael
