kernel: Linux kernel KVM: Privilege escalation or denial of service due to improper shadow page table entry handling
A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. A local attacker with privileges on the host system could exploit a vulnerability in how KVM handles shadow page table entries SPTEs during memory-mapped I/O MMIO operations. By manipulating guest page table entrie...
PT-2026-61489
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the KVM SVM implementation for Hygon Family 18h CPUs. Due to a hardware erratum, the system may read a stale IsRunning=1 bit during ICR write emulation. This causes a...

Summary Storage Virtualize Ansible Collection uses the cryptography package to provide common cryptographic algorithms. Version cryptography-46.0.5 package is vulnerable to CVE-2026-39892. Vulnerability Details Refer to the security bulletins listed in the Remediation/Fixes section Affected...
libusb: libusb: Denial of Service via malformed USB configuration descriptor
A flaw was found in libusb. An attacker can provide a specially crafted Universal Serial Bus USB configuration descriptor to applications using libusb. This malformed descriptor can lead to a null pointer dereference, causing the application to crash and resulting in a denial of service. This...
libusb: libusb: Denial of Service via malformed USB descriptor
A flaw was found in libusb. This out-of-bounds read vulnerability allows a local attacker, particularly in virtualized environments utilizing USB passthrough, to trigger a denial of service. By providing a malformed USB descriptor, the attacker can cause the software to read beyond its allocated...

In the Linux kernel, the following vulnerability has been resolved: mm: gup: stop abusing trygrabfolio A kernel warning was reported when pinning folio in CMA memory during the launch of the SEV virtual machine. The error message looks like this: 464.325306 WARNING: CPU: 13 PID: 6734 at...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: KVM: x86: nSVM: fixed a potential NULL dereference during nested migration. It turns out that due to feedback from reviews and/or changes in relocation locations, I accidentally moved the call to nestedsvmloadcr3 too early, befor...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: igb: Clean up operations in all error paths when enabling SR-IOV After commit 50f303496d92 “igb: Enabling SR-IOV after reinit”, removing the igb module could cause a hang or crash depending on the machine when the module was load...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: A WARN message is generated on vNMI when an NMI window is requested, provided that the NMIs are effectively masked. This occurs only if the vCPU is already handling an NMI. KVM’s approach for handling simultaneous NMIs ...
