Astra Linux – Vulnerability in amd64-microcode

Improper signature verification in the AMD CPU ROM microcode patch loader may allow an attacker with local administrator privileges to load malicious CPU microcode, resulting in a loss of confidentiality and integrity for confidential guests running under AMD SEV-SNP...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: KVM: x86 – Mark the target gfn of the emulated atomic instruction as dirty When emulating an atomic access on behalf of the guest, mark the target gfn as dirty if the CMPXCHG instruction attempts to be executed and fails without ...

Astra Linux – Vulnerability in Linux 5.10, Linux

A flaw was discovered in KVM. When updating a guest’s page table entry, vmpgoff was incorrectly used as the offset to obtain the page’s pfn. Since vaddr and vmpgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Zap all roots when unmapping gfn range in TDP MMU Both valid and invalid roots are cleared when unmapping a gfn range. KVM must ensure that it does not hold any references to the freed page after the unmapping...

Astra Linux – Vulnerability in amd64-microcode

IOMMU improperly handles certain special address ranges with invalid device table entries DTEs. This may allow an attacker with privileges and a compromised Hypervisor to induce DTE faults to bypass RMP checks in SEV-SNP, potentially resulting in a loss of guest integrity...

Astra Linux – Vulnerability in virglrenderer

A heap-based buffer overflow in the vrendrenderertransferwriteiov function in vrendrenderer.c in virglrenderer from version 0.8.0 allows guest OS users to cause a denial of service, or a QEMU guest-to-host escape and code execution, through VIRGLCCMDRESOURCEINLINEWRITE commands...

Astra Linux – Vulnerability in libvirt

A flaw was discovered in the libvirt libxl driver. A malicious guest could continuously reboot itself, causing libvirtd on the host to become locked out or crash, resulting in a denial-of-service condition...

Astra Linux – Vulnerability in Linux

The fix for XSA-365 includes the initialization of pointers so that subsequent cleanup code would not use uninitialized or stale values. However, this initialization went too far and may, under certain conditions, also overwrite pointers that need to be cleaned up. The lack of cleanup would resul...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: making the apf token non-zero to fix the bug In the current async pagefault logic, when a page is ready, KVM relies on kvmarchcandequeuepagepresent to determine whether to deliver a READY event to the Guest. This...

Astra Linux – Vulnerability in Linux

The file arch/powerpc/kvm/book3srtas.c in the Linux kernel, as of version 5.13.5 on the PowerPC platform, allows KVM guest OS users to cause memory corruption in the host OS through rtasargs.nargs, also known as CID-f62f3c20647e...

Astra Linux – Vulnerability in Qemu

A reentrancy issue related to DMA operations led to a use-after-free error in the e1000e NIC emulation code in QEMU. This issue could allow a privileged guest user to crash the QEMU process on the host, resulting in a denial of service...

Astra Linux – Vulnerability in Qemu

A stack-based buffer overflow was discovered in the virtio-net device of QEMU. This issue occurs when flushing the TX operation in the virtionetflushtx function, provided that the guest has enabled VIRTIONETFHASHREPORT, VIRTIOFVERSION1, and VIRTIONETFMRGRXBUF. This could allow a malicious user to...

Astra Linux – Vulnerability in Linux, Linux 5.10

A guest can force the Linux netback driver to consume a large amount of kernel memory. This CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVEs. Incoming data packets for a guest in the Linux kernel’s netback driver are buffere...

Astra Linux – Vulnerability in Chromium

The use of “after free” in the Guest View of Google Chrome before version 114.0.5735.198 allowed an attacker who convinced a user to install a malicious extension to potentially exploit heap corruption through a crafted HTML page. Chromium security severity: High...

Astra Linux – Vulnerability in Linux 5.15

A flaw was discovered in KVM AMD Secure Encrypted Virtualization SEV within the Linux kernel. A KVM guest that uses SEV-ES or SEV-SNP with multiple vCPUs can trigger a double fetch race condition vulnerability and invoke the VMGEXIT handler recursively. If an attacker manages to call the handler...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: The existing SPTE is dropped/zapped even when creating an MMIO SPTE. When installing an emulated MMIO SPTE, do so after dropping/zapping the existing SPTE if it’s shadow-present. While the commit a54aa15c6bda3 was...

Astra Linux – Vulnerability in Linux 6.1

Improper initialization of the CPU cache memory could allow a privileged attacker with access to the hypervisor to overwrite the SEV-SNP guest memory, resulting in loss of data integrity...
