Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic-v2: Check whether the vCPU is not NULL in vgicv2parseattr. vgicv2parseattr is responsible for finding the vCPU that matches the user-provided CPUID. This CPUID may, of course, be invalid. If the ID is invalid,...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: LoongArch: KVM: Make kvmgetvcuByCPUid more robust The kvmgetvcuByCPUid function takes a cpuid parameter whose type is int; therefore, the cpuid value can be negative.

CVE-2026-43315

CVE-2026-43315 involves the Linux kernel KVM nSVM warning path. Technical details across connected docs show that a user-triggerable WARN is raised in svm_set_nested_state() when nested_svm_load_cr3() succeeds, and the patch removes this WARN. The rationale is that userspace can easily trigger th...
