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 ...

CVE-2026-89907

CVE-2026-89907 affects the Linux kernel on the LoongArch architecture in the KVM EIOINTC MSI routing path. The function pch_msi_set_irq() passes user-supplied MSI data directly to eiointc_set_irq() without validating it against the 256-entry EIOINTC_IRQS limit. A value of 256 or greater causes ou...

CVE-2026-89906

CVE-2026-89906 affects the LoongArch BPF JIT in the Linux kernel. The jump offset calculation for tail calls used a stale prior-pass code stride to derive branch distances, which can produce wrong branch offsets and cause soft lockups when extra JIT passes are triggered. The fix recalculates the ...
