CVE-2026-72294

The CVE-2026-72294 case affects the Linux kernel on LoongArch under KVM. The vulnerable component is kvm_vcpu_ioctl_interrupt() where irq validity checking was previously missing, allowing potential misvalidation when called from userspace. The root cause is insufficient validation of IRQs in the...
