CVE-2026-23128: arm64: Set __nocfi on swsusp_arch_resume()

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: 0.17% (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 122b7cb80f7d468fcc2d18cf7eb320f09f310a96, 6e32070d29d1a35d8f4b3c03babf6c0e5efd1d08, 8557bdd9af8dd04911fba56ff92b17842b0b5c7f.

Low priority for now. Upgrade to Linux Linux 122b7cb80f7d468fcc2d18cf7eb320f09f310a96, 6e32070d29d1a35d8f4b3c03babf6c0e5efd1d08, 8557bdd9af8dd04911fba56ff92b17842b0b5c7f or later.

In the Linux kernel, the following vulnerability has been resolved: arm64: Set __nocfi on swsusp_arch_resume() A DABT is reported[1] on an android based system when resume from hiberate. This happens because swsusp_arch_suspend_exit() is marked with SYM_CODE_*() and does not have a CFI hash, but swsusp_arch_resume() will attempt to verify the CFI hash when calling a copy of swsusp_arch_suspend_exit(). Given that there's an existing requirement that the entrypoint to swsusp_arch_suspend_exit() is the first byte of the .hibernate_exit.text section, we cannot fix this by marking swsusp_arch_suspend_exit() with SYM_FUNC_*(). The simplest fix for now is to disable the CFI check in swsusp_arch_resume(). Mark swsusp_arch_resume() as __nocfi to disable the CFI check.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
