CVE-2026-64592

Popis

In the Linux kernel, the following vulnerability has been resolved: riscv: mm: Unconditionally sfence.vma for spurious fault Svvptc does not guarantee that it-s safe to just return here. Since we have already cleared our bit, if, theoretically, the bounded timeframe for the accessed page to become valid still hasn-t happened after sret, we could fault again and actually crash. Hopefully, these spurious faults should be rare enough that this is an acceptable slowdown.
