CVE-2026-90012 spi: Fix DMA mapping ownership on partial map failure

In the Linux kernel, the following vulnerability has been resolved: spi: Fix DMA mapping ownership on partial map failure If RX mapping fails after TX mapping succeeds, spimapmsg unmaps TX but leaves txsgmapped set. If TX mapping fails on a later transfer, mappings created for earlier transfers...

CVE-2026-89977 accel/ethosu: check MMIO mapping errors in probe

In the Linux kernel, the following vulnerability has been resolved: accel/ethosu: check MMIO mapping errors in probe devmplatformioremapresource returns an error pointer when the register resource cannot be mapped. ethosuprobe stores it and continues until initialization dereferences it through...

CVE-2026-89977

CVE-2026-89977 affects the accel/ethosu driver in the Linux kernel . The root cause is a missing error check: devm_platform_ioremap_resource() can return an error pointer when the register resource cannot be mapped, but ethosu_probe() stores the pointer and continues execution until later initial...

CVE-2026-89961

CVE-2026-89961 affects the Linux kernel 's powerpc/mm subsystem, specifically the vmemmap_populate_compound_pages() function. The root cause is a mismatch in how addr_pfn is advanced relative to the loop's addr variable in vmemmap address space. Because each PAGE_SIZE step in addr spans PAGE_SIZE...

CVE-2026-89931

CVE-2026-89931 affects the Linux kernel's KVM nVMX (nested virtualization) subsystem. The root cause is that the KVM_REQ_GET_NESTED_STATE_PAGES flag is not reliably cleared when emulating a nested VM-Exit, specifically when KVM is built with CONFIG_KVM_HYPERV=n . Because KVM implicitly relies on ...

CVE-2026-89908

In the Linux kernel LoongArch KVM subsystem, kvm_arch_prepare_memory_region() computes a memslot's arch.flags (KVM_MEM_HUGEPAGE_CAPABLE / KVM_MEM_HUGEPAGE_INCAPABLE) only for KVM_MR_CREATE and KVM_MR_MOVE, returning early for all other changes. Because the generic code allocates a zeroed memslot ...
