CVE-2026-64592

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 becom...

CVE-2026-64592

CVE-2026-64592 affects the Linux kernel on riscv, in the memory management path handling spurious faults. The issue arises from unconditionally performing sfence.vma after a spurious fault, after the Svvptc path has cleared its bit; if the page becomes valid only after sret, a subsequent fault co...

PT-2026-68425

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the RISC-V memory management where the Svvptc instruction does not guarantee safety upon return. If the bounded timeframe for an accessed page to become valid has not...
