Hi,

please backport the following commit[0] to all stable releases that contain the commit 226fae124b2d ("vc_screen: move load of struct vc_data pointer in vcs_read() to avoid UAF")

Commit 46d733d0efc7 ("vc_screen: modify vcs_size() handling in vcs_read()") [1] also tries to fix this commit but should not actually be necessary for a proper fix. It may make sense to also backport for consistency.

Now queued up, thanks.
