CVE-2025-68737

Estado: AplazadaSin puntuar—

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.
