CVE-2025-38047: x86/fred: Fix system hang during S4 resume with FRED enabled

MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.19% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux c42f740a07eea4807e98d2d8febc549c957a7b49, e5f1e8af9c9e151ecd665f6d2e36fb25fec3b110, e7090fe75a2826363c71ad1fb4e95e58141478df.

Low priority for now. Upgrade to Linux Linux c42f740a07eea4807e98d2d8febc549c957a7b49, e5f1e8af9c9e151ecd665f6d2e36fb25fec3b110, e7090fe75a2826363c71ad1fb4e95e58141478df or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: x86/fred: Fix system hang during S4 resume with FRED enabled Upon a wakeup from S4, the restore kernel starts and initializes the FRED MSRs as needed from its perspective. It then loads a hibernation image, including the image kernel, and attempts to load image pages directly into their original page frames used before hibernation unless those frames are currently in use. Once all pages are moved to their original locations, it jumps to a "trampoline" page in the image kernel. At this point, the image kernel takes control, but the FRED MSRs still contain values set by the restore kernel, which may differ from those set by the image kernel before hibernation. Therefore, the image kernel must ensure the FRED MSRs have the same values as before hibernation. Since these values depend only on the location of the kernel text and data, they can be recomputed from scratch.
