In the Linux kernel, the following vulnerability has been resolved: LoongArch: KVM: Fix base address calculation in kvmeiointcregsaccess In function kvmeiointcregsaccess, the register base address is caculated from array base address plus offset, the offset is absolute value from the base address...

CVE-2026-31564

CVE-2026-31564 (LoongArch KVM) : The Linux kernel fix addresses a faulty address calculation in the LoongArch KVM implementation, specifically in kvm_eiointc_regs_access(). The code previously derived the register base address by adding an offset to an array base address treated as a u64, which c...

CVE-2026-31558

The CVE-2026-31558 issue affects the Linux kernel LoongArch KVM component. The vulnerable code is kvm_get_vcpu_by_cpuid(), which accepts a cpuid as int; if cpuid is negative, the function could access kvm_arch::phyid_map::phys_map[] out of bounds. The documented fix makes kvm_get_vcpu_by_cpuid() ...

CVE-2026-31559

This CVE (CVE-2026-31559) affects the LoongArch implementation in the Linux kernel. The issue is a missing NULL check in kstrdup() during device-tree processing, fixed by replacing of_find_node_by_path("/") with of_root to avoid multiple of_node_put() calls, and by preventing a kernel oops during...
