CVE-2025-40181

CVE-2025-40181 : In the Linux kernel x86/kvm, when running as an SNP/TDX guest, forcing the legacy PCI hole to UC by overriding MTRRs can cause ACPI-reported SystemMemory regions mapped as WB to conflict with device memory WC/UC requirements. This can lead to ioremap() failures for PCI devices (e...

kernel: netfs: Fix early read unlock of page with EOF in middle

A race condition flaw was found in the Linux kernel's netfs subsystem. In the netfsreadunlockfolios function, a folio memory page may be unlocked prematurely before the ZERO subrequest completes clearing the tail portion of the page beyond the end-of-file. This allows an application using mmap to...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: perf/core: Prevents VMA splitting of buffer mappings. The perfmmap code is careful to map the user page using mmap along with the ringbuffer and the auxiliary buffer, when the event supports this. Once the first mapping is...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Process deferred GGTT node removals upon device unwinding. While we are indirectly draining our dedicated workqueue ggtt-wq—which we use to perform asynchronous removal of certain GGTT nodes—this occurs as part of the...

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...
