| sbeattie | in the short term, Ubuntu 6.6 based kernels (Ubuntu 23.10 LTS and Ubuntu 22.04 HWE kernels) have backported the first round of native_bhi mitigations, but are defaulting to spectre_bhi=auto. The kernel commandline parameter can be changed to spectre_bhi=on if desired; see the kernel parameters documentation linked to in the references section. This default will change to match the upstream kernel’s default to “on” in a subsequent update. |
| rodrigo-zaiden | USN-6765-1 for linux-oem-6.5 wrongly stated that this CVE was fixed in version 6.5.0-1022.23. The mentioned notice was revoked and the state of the fix for linux-oem-6.5 was recovered to the previous state. |
| apw | patches #1 and #7 are not expected before jammy they were not required for mitigation; make them both conditional on v5.15 being present. |
