Package : linux
Version : 4.19.289-2
CVE ID : CVE-2022-40982

Daniel Moghimi discovered Gather Data Sampling (GDS), a hardware
vulnerability for Intel CPUs which allows unprivileged speculative
access to data which was previously stored in vector registers.

This mitigation requires updated CPU microcode provided in the
intel-microcode package.

For details please refer to <https://downfall.page/> and
<https://www.intel.com/content/www/us/en/developer/articles/technical/software-security-guidance/technical-documentation/gather-data-sampling.html>.

For Debian 10 buster, this problem has been fixed in version
4.19.289-2.

We recommend that you upgrade your linux packages.
