It appears they do. Here's what the patch description says:
"openSUSE-2018-1 - Security update for kernel-firmware
This update for kernel-firmware fixes the following issues: - Add microcode_amd_fam17h.bin (bsc#1068032 CVE-2017-5715) This new firmware disables branch prediction on AMD family 17h processor to mitigate a attack on the branch predictor that could lead to information disclosure from e.g. kernel memory (bsc#1068032 CVE-2017-5715)."
So with intel this doesn't help and must not be installed?
For Intel the update is "ucode-intel". it is just part of the fix, the kernel update is needed to implement it. Ciao, Marcus -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
