In the Linux kernel, the following vulnerability has been resolved: arm64/pageattr: Propagate return value from __change_memory_common The rodata=on security measure requires that any code path which does vmalloc -> set_memory_ro/set_memory_rox must protect the linear map alias too. Therefore, if such a call fails, we must abort set_memory_* and caller must take appropriate action; currently we are suppressing the error, and there is a real chance of such an error arising post commit a166563e7ec3 ("arm64: mm: support large block mapping when rodata=full"). Therefore, propagate any error to the caller.
Conclusion & alert: CVE-2025-68737 is rated Low Risk (5.5/100): low exploitation likelihood (EPSS 0.16%). Mandatory action: Low composite risk—no urgent action required; patch on your normal maintenance cycle and revisit priority if CVSS or EPSS increases.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
EPSS lead: Daily EPSS estimates relative likelihood of exploitation; percentile ranks this CVE among scored vulnerabilities (higher = more severe relative rank).
