Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: vsock/vmci: The vmci transport packet should be cleared properly when initializing it. In vmcitransportpacketinit, memset is used to clear the vmcitransportpacket before populating the fields, to avoid any uninitialized data...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: using arrayindexnospec with indices that come from the guest min and destid are guest-controlled indices. Using arrayindexnospec after the bounds checks helps to mitigate speculative execution side-channels by clamping...

EUVD-2025-37346

When passing through PCI devices, the detach logic in libxl won't remove access permissions to any 64bit memory BARs the device might have. As a result a domain can still have access any 64bit memory BAR when such device is no longer assigned to the domain. For PV domains the permission leak allo...

USN-7850-1: Linux kernel vulnerabilities

Jean-Claude Graf, Sandro Rüegge, Ali Hajiabadi, and Kaveh Razavi discovered that the Linux kernel contained insufficient branch predictor isolation between a guest and a userspace hypervisor for certain processors. This flaw is known as VMSCAPE. An attacker in a guest VM could possibly use this t...

CVE-2025-40086

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Don't allow evicting of BOs in same VM in array of VM binds An array of VM binds can potentially evict other buffer objects BOs within the same VM under certain conditions, which may lead to NULL pointer dereferences late...

CVE-2025-40102

CVE-2025-40102 affects the Linux kernel KVM/ARM64: an attacker could access vCPU events before a vCPU is initialized, leading to misinterpretation of uninitialized data and potential exception handling issues. The description and connected advisories (EulerOS kernel advisories) confirm this as a ...

CVE-2025-40086

CVE-2025-40086 affects the Linux kernel DRM XE path. An array of VM binds could evict other buffer objects (BOs) within the same VM, potentially causing NULL pointer dereferences in the bind pipeline. The fix clears the allow_res_evict flag in xe_bo_validate (and there was a follow‑up commit that...
