Any implications for KDE?

Until they release Plasma 6 (which uses Qt 6), they will use Qt5PatchCollection:
Qt5PatchCollection (https://community.kde.org/Qt5PatchCollection) is a set of git repositories based on the last public commits available for Qt 5.15 branches with a curated collection of patches on top to ensure open source products can be used comfortably until users transition to their Qt 6-based ports.

Its latest commits can be seen on https://invent.kde.org/qt/qt/qtbase/-/commits/kde/5.15

For those using 5.15 qtwebengine (I'm sure you all know it has different licensing and is therefore in public git trees) the big question is whether any more chromium vulnerability fixes will be backported to the 87 tree that 5.15 uses.
