CVE-2025-38506

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.15.0-rc7.20250520.el9uek.rc1.x86 64
Description: The Linux kernel contained a flaw where the CPU could become locked up while setting per-page memory attributes during operation in kvm vm set mem attributes() with a sufficiently large amount of memory (1TB+), specifically when running an SEV-SNP guest. This could occur when setting memory attributes on the whole range of guest memory, potentially leading to CPU soft lockups.
Recommendations: Update the Linux kernel to a version later than 6.15.0-rc7.20250520.el9uek.rc1.x86 64.
