Hi guys,
While booting up I get a scary message saying:
L1TF CPU bug present and SMT on, data leak possible.
Yup you guessed it, I am on an Intel processor, which is in fact quiet old:
Intel(R) Core(TM) i5-6200U CPU
Vulnerability info from the kernel:
cat /sys/devices/system/cpu/vulnerabilities/l1tf
Mitigation: PTE Inversion; VMX: conditional cache flushes, SMT vulnerable
I am in the process of reading this detailed article about the bug:
https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/l1tf.html
Meanwhile, I wanted to know if any one here has the same problem and
what they did for mitigations.
The scariest thing about this bug, specifically, is that even malicious
VMs pose a threat. May speculative execution burn in hell.
I am no expert on hardware or these types of obscure vulnerabilities so
any advice/tips/help is greatly appreciated.
PS: I thought of going to a kernel mailing list, but am worried that
those "geniuses" would just flame me.
