** Description changed: Hi, Recently you would have been notified about CVE-2019-18660 via email to the linux-distros private mailing list. In short, it is a bug in the Spectre v2 class affecting powerpc. We have developed some backports for supported Ubuntu kernels, and tested them in our lab. I will attach the patches shortly. Most of them should end up being identical to the versions in linux-stable, but the ones for Bionic are slightly different due to it using a 4.15 kernel. Please get in touch with me or Michael Ellerman (powerpc maintainer) if you have any questions or if we can be of any assistance. - If I understand the SRU cycles correctly, we've missed the current one - due for release on 2 December, so the earliest these patches could land - in is the kernel nominally slated to be released ~23 December. Are you - planning to still release a kernel then, or are your cycles going to - change over the end of year period? - - (If it helps, we've got some automation set up so we're able to do the - regression testing of -proposed kernels with these patches quickly.)
