I just discovered the spectre-meltdown-checker package (thanks Sylvestre for packaging this).
model name : Intel(R) Core(TM)2 Quad CPU Q9505 @ 2.83GHz On a system with the above CPU running Debian/Testing I get the following results from the spectre-meltdown-checker script. Is this a bug in the intel- microcode package that the latest version isn't packaged? There is no newer version of intel-microcode in Unstable. # spectre-meltdown-checker |grep CPU.mic * Hardware support (CPU microcode) for mitigation techniques * CPU microcode is known to cause stability problems: NO (model 0x17 family 0x6 stepping 0xa ucode 0xa0b cpuid 0x1067a) * CPU microcode is the latest known available version: NO (latest version is 0xa0e dated 2015/07/29 according to builtin MCExtractor DB v111 - 2019/05/18) IBPB is considered as a good addition to retpoline for Variant 2 mitigation, but your CPU microcode doesn't support it * CPU microcode mitigates the vulnerability: NO > STATUS: VULNERABLE (an up-to-date CPU microcode is needed to mitigate this vulnerability) * CPU microcode mitigates the vulnerability: N/A -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
