More information:

Linux 5.10 has been packaged for Debian 10 as linux-5.10. This provides a supported upgrade path for systems that currently use kernel packages from the "buster-backports" suite.

There is no need to upgrade systems using Linux 4.19, as that kernel version will also continue to be supported in the LTS period.

The "apt full-upgrade" command will not automatically install the updated kernel packages. You should explicitly install one of the following metapackages first, as appropriate for your system:

  • linux-image-5.10-686
  • linux-image-5.10-686-pae
  • linux-image-5.10-amd64
  • linux-image-5.10-arm64
  • linux-image-5.10-armmp
  • linux-image-5.10-armmp-lpae
  • linux-image-5.10-cloud-amd64
  • linux-image-5.10-cloud-arm64
  • linux-image-5.10-rt-686-pae
  • linux-image-5.10-rt-amd64
  • linux-image-5.10-rt-arm64
  • linux-image-5.10-rt-armmp

For example, if the command "uname -r" currently shows "5.10.0-0.deb10.16-amd64", you should install linux-image-5.10-amd64.

This backport does not include the following binary packages:

bpftool hyperv-daemons libcpupower-dev libcpupower1 linux-compiler-gcc-8-arm linux-compiler-gcc-8-x86 linux-cpupower linux-libc-dev usbip

Older versions of most of those are built from the linux source package in Debian 10.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

For Debian 10 buster, these problems have been fixed in version 5.10.136-1~deb10u3. This update additionally includes many more bug fixes from stable updates 5.10.128-5.10.136 inclusive.

We recommend that you upgrade your linux-5.10 packages.
