CVE-2025-68737

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> arm64/pageattr: Propagate return value from __change_memory_common<br /> <br /> The rodata=on security measure requires that any code path which does<br /> vmalloc -&gt; set_memory_ro/set_memory_rox must protect the linear map alias<br /> too. Therefore, if such a call fails, we must abort set_memory_* and caller<br /> must take appropriate action; currently we are suppressing the error, and<br /> there is a real chance of such an error arising post commit a166563e7ec3<br /> ("arm64: mm: support large block mapping when rodata=full"). Therefore,<br /> propagate any error to the caller.
