CVE-2025-61972

Missing lock bit protection for NBIO registers could allow a local admin-privileged attacker to gain arbitrary System Management Network SMN access, potentially resulting in arbitrary code execution in AMD Secure Processor ASP and loss of the SEV-SNP guest's confidentiality and integrity...

CVE-2026-0438

A flaw was found in microcodectl. A System Management Mode SMM handler, a special CPU operating mode, could allow a callout to untrusted memory. A highly privileged attacker, with active user interaction and specific preconditions, could exploit this to execute arbitrary code within SMM. This cou...

CVE-2024-36343

Improper input validation in the System Management Mode SMM communications buffer could allow a privileged attacker to perform an out of bounds read or write to a limited section of the Top of Memory Segment TSEG memory region, potentially resulting in loss of confidentiality or integrity...

CVE-2024-36345

Improper input validation in the AMD OverDrive AOD System Management Mode SMM module could allow a privileged attacker to perform an out-of-bounds read, potentially resulting in loss of confidentiality...

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, 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...

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...
