In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Forcing the SMM mode to remain active during SHUTDOWN interception Previously, the commit ed129ec9057f “KVM: x86: forcing the nested mode to remain active during vCPU reset” addressed an issue where a triple fault...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: smm: the number of GPRs in the SMRAM image depends on the image format. On 64-bit hosts, if the guest does not have X86FEATURELM, KVM will access 16 GPRs for a 32-bit SMMR image, resulting in an out-of-bound RAM access...

Astra Linux - уязвимость в linux, linux-5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Immediately reset the MMU context when the SMM flag is cleared The MMU context should be immediately reset when the SMM flag of the vCPU is cleared, so that the SMM flag in the MMU context is always synchronized with th...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Forcibly leave nested virtualization mode when SMM state is toggled The nested virtualization mode is forcibly exited if the user space toggles the SMM state using KVMSETVCPUEVENTS or KVMSYNCX86EVENTS. If the user space...

Astra Linux - уязвимость в linux-6.1

In the Linux kernel, the following vulnerabilities have been resolved: KVM: x86: Acquiring kvm-srcu when handling KVMSETVCPUEVENTS Acquire kvm-srcu when processing KVMSETVCPUEVENTS. When KVM sets the SMM mode, it forcibly leaves the nested VMX/SVM state. Leaving such a state also causes nested VM...
