Release/update 11.1-p8 introduced so-called "mitigation for speculative execution vulnerabilities". In RElease 11.2 these "mitigation" have been removed. What is the reason for the removal, and specifically why is Security advisory 18:03 still mentioned in the release notes? Behaviour with 11.1-p8: # sysctl hw.ibrs_disable hw.ibrs_disable: 0 # sysctl hw.ibrs_active hw.ibrs_active: 1 Behaviour with 11.2 w/ same CPU + microcode: # sysctl hw.ibrs_disable hw.ibrs_disable: 0 # sysctl hw.ibrs_active hw.ibrs_active: 0
