Greg Kroah-Hartman just released the Linux 6.15.6 point release as well as the Linux 6.12.37 LTS kernel and new point releases in prior-year Long Term Support kernel versions. The main headline of today’s stable kernel releases are picking up the mitigations for the Transient Scheduler Attacks (TSA) mitigations that were disclosed this week for AMD processors.
Back on Patch Tuesday, the Linux 6.16 Git kernel saw the mitigation work merged for the newly-disclosed Transient Scheduler Attacks as a new class of side channel attacks affecting some AMD processors. Kernel patches are needed for the TSA mitigation as well as CPU microcode or system firmware updates.
Today’s round of Linux stable kernel releases bring the TSA mitigations from Linux Git to the respectable stable branches. Plus various other fixes too that are back-ported.
Today’s versions include Linux 6.15.6 as the newest current kernel series and then for the Long Term Support series are 6.12.37, 6.6.97, 6.1.144, and 5.15.187. Just the AMD TSA mitigation patches and various other back-ported fixes.
Linux 6.16-rc6 meanwhile will be out on Sunday as the next upstream kernel version and working its way toward the stable Linux 6.16 kernel debut around the end of July.
