CVSS 3.1
5.5 mediumCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:HCVE-2025-38518
Medium (5.5) in linux linux kernel. EPSS 0.1% chance of exploitation in the next 30 days.
In the Linux kernel, the following vulnerability has been resolved:
x86/CPU/AMD: Disable INVLPGB on Zen2
AMD Cyan Skillfish (Family 17h, Model 47h, Stepping 0h) has an issue
that causes system oopses and panics when performing TLB flush using
INVLPGB.
However, the problem is that that machine has misconfigured CPUID and
should not report the INVLPGB bit in the first place. So zap the
kernel's representation of the flag so that nothing gets confused.
