CVE-2025-71089

CVE-2025-71089 affects the Linux kernel via IOMMU Shared Virtual Addressing (SVA). In SVA, the IOMMU can cache kernel page-table entries, so freeing a kernel page-table page and reusing it could leave stale IOMMU entries, enabling use-after-free or write-after-free scenarios that could allow loca...

CVE-2025-71078

In the Linux kernel, the following vulnerability has been resolved: powerpc/64s/slb: Fix SLB multihit issue during SLB preload On systems using the hash MMU, there is a software SLB preload cache that mirrors the entries loaded into the hardware SLB buffer. This preload cache is subject to period...

CVE-2025-71078

CVE-2025-71078 describes a Linux kernel fix for a SLB multihit issue on hash MMU POWERPC 64s. The root cause is a mismatch between the hardware SLB and the software preload cache when the kernel optimizes switch_mm_irqs_off by not calling switch_mmu_context() if prev and next mm_struct are the sa...

CVE-2025-71069
