Stéphane Lesimple a20641fbad fix: handle non-numeric ARM CPU architecture values 
Some old ARM processors (e.g., ARM926EJ-S) report CPU architecture
with suffix in /proc/cpuinfo (e.g., "5TEJ" for ARMv5TEJ).

This caused an "integer expression expected" error when comparing
against numeric values. Extract the numeric prefix before integer comparisons.

Fixes #505.

Stéphane Lesimple d550ea8c85 fix: harmless 'dmesg: write error' that could happen on some systems 
Fixes #519.
 2026-01-25 11:53:13 +01:00
Stéphane Lesimple 8e33a1dbf2 fix: set cpu_* vars to a default value 
On ARM64 systems, /proc/cpuinfo uses different field names (CPU implementer,
CPU variant, CPU part, CPU revision) instead of x86-style fields (cpu family,
model, stepping). This left these variables empty, causing printf to fail
with 'invalid number' errors when formatting them as hex values.

Fixes #520.

Stéphane Lesimple f34dd5fa7b enh: assume CPU is immune to Zenbleed regardless of vendor except AMD 
This contradicts our usual "if we don't know, consider vulnerable" motto,
but as this vuln is extremely specific (which is not the case for the Spectre
range of vulnerabilities, for example), this is the correct approach here.
