Subject: /sys/devices/system/cpu/vulnerabilities/ doesn't show all known CPU vulnerabilities
Date: Tue, 13 Aug 2019 23:28:29 +0300 [thread overview]
Message-ID: <20190813232829.3a1962cc@localhost> (raw)
Hi,
'ls /sys/devices/system/cpu/vulnerabilities/' doesn't show all known
CPU vulnerabilities and their variants. Only some of them:
l1tf mds meltdown spec_store_bypass spectre_v1 spectre_v2
Wikipedia shows more variants:
https://en.wikipedia.org/wiki/Meltdown_(security_vulnerability)#Speculative_execution_security_vulnerabilities
It would be good to have a full list with statuses. Then one won't need to use external (potentially non-safe) tools like https://github.com/speed47/spectre-meltdown-checker to find out the vulnerabilities of a system.
This started as a feature request on openSUSE's bugzilla where it was
suggested to report it here:
