Linux 6.4.6 and Mesa 23.1.3 Released

These updates will improve performance, bring more hardware compatibility, fix various issues, and most importantly of all, resolves some outstanding major security vulnerabilities that were recently discovered to affect all kernels from 6.1.0 through 6.4.1.

There is, however, a known regression with USB-C docks on 12th (ADL) and 13th (RPL) generation Intel laptops which causes occasional system freezes. There are some known workarounds here. USB-C to DisplayPort is not affected.

We've decided not to delay the kernel update any further because fixing the vulnerabilities are more important. In the meantime, there is an issue on Intel's DRM repository for tracking this issue: https://gitlab.freedesktop.org/drm/intel/-/issues/8421. We will quickly patch the regression the moment that we or Intel finds the cause and solution.
