CVE-2026-46044

A flaw was found in the Linux kernel's Intelligent Platform Management Interface IPMI SSIF SMBus System Interface driver. If an error occurs after a kernel thread kthread is created but before the main IPMI code initializes the SSIF interface, the kthread may not be properly stopped. This could...

UBUNTU-CVE-2026-46044

In the Linux kernel, the following vulnerability has been resolved: ipmi:ssif: Clean up kthread on errors If an error occurs after the ssif kthread is created, but before the main IPMI code starts the ssif interface, the ssif kthread will not be stopped. So make sure the kthread is stopped on an...

Astra Linux – Vulnerability in 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 – Vulnerability in 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 to the 32-bit SMMR image, resulting in an out-of-bound RAM access...

Astra Linux – Vulnerability in 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 must be reset immediately when the SMM flag of the vCPU is cleared, so that the SMM flag in the MMU context is always synchronized with the...
