CVE-2024-35801 (GCVE-0-2024-35801)

Vulnerability from cvelistv5 – Published: 2024-05-17 13:23 – Updated: 2026-05-11 20:11

Title

x86/fpu: Keep xfd_state in sync with MSR_IA32_XFD

Summary

In the Linux kernel, the following vulnerability has been resolved: x86/fpu: Keep xfd_state in sync with MSR_IA32_XFD Commit 672365477ae8 ("x86/fpu: Update XFD state where required") and commit 8bf26758ca96 ("x86/fpu: Add XFD state to fpstate") introduced a per CPU variable xfd_state to keep the MSR_IA32_XFD value cached, in order to avoid unnecessary writes to the MSR. On CPU hotplug MSR_IA32_XFD is reset to the init_fpstate.xfd, which wipes out any stale state. But the per CPU cached xfd value is not reset, which brings them out of sync. As a consequence a subsequent xfd_update_state() might fail to update the MSR which in turn can result in XRSTOR raising a #NM in kernel space, which crashes the kernel. To fix this, introduce xfd_set_state() to write xfd_state together with MSR_IA32_XFD, and use it in all places that set MSR_IA32_XFD.

But the per CPU cached xfd value is not\nreset, which brings them out of sync.\n\nAs a consequence a subsequent xfd_update_state() might fail to update\nthe MSR which in turn can result in XRSTOR raising a #NM in kernel\nspace, which crashes the kernel.\n\nTo fix this, introduce xfd_set_state() to write xfd_state together\nwith MSR_IA32_XFD, and use it in all places that set MSR_IA32_XFD."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
