Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: pciiounmap: Fixed the MMIO mapping leak. The ifdef ARCHHASGENERICIOPORTMAP condition accidentally also guards iounmap, which means MMIO mappings are leaked. We have moved the guard so that we call iounmap for MMIO mappings...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: gpio: qixis-fpga: Fixed error handling for devmregmapinitmmio. devmregmapinitmmio returns ERRPTR if it fails, instead of returning NULL. The original code checked for NULL, which would never trigger an error, potentially leading ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: Watchdog: sp5100tco – Fixed a memory leak related to the EFCH MMIO resource. Unlike releasememregion, a call to releaseresource does not free the resource automatically; therefore, it must be freed explicitly to avoid a memory...

Astra Linux – Vulnerability in Qemu

A buffer overflow vulnerability was discovered in the ATI VGA device emulation provided by QEMU. This vulnerability occurs in the ati2dblt routine, during the handling of MMIO write operations, when the guest provides invalid values for the destination display parameters. A malicious guest could...

Astra Linux – Vulnerability in Qemu

QEMU 4.2.0 has a use-after-free issue in hw/net/e1000ecore.c, as a user of the guest OS can trigger an e1000e packet with the data’s address set to the e1000e’s MMIO address...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: virtio-mmio: Do not break the lifecycle of vmdev. vmdev has a separate lifecycle because it has a struct device embedded within it. Therefore, having a release callback for it is correct. However, allocating the vmdev structure...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel/uncore: A reference count leak was fixed in snruncoremmiomap. pcigetdevice will increase the reference count of the returned pcidev. Therefore, snruncoregetmcdev will return a pcidev with its reference count...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Drivers: hv: vmbus: Do not dereference the ACPI root object handle Since the commit referenced in the Fixes section below the VMBus client driver attempts to traverse the ACPI namespace from the VMBus ACPI device to the ACPI...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/xe/vf: Early GT MMIO initialization is required to read the GMDID. VFs need to communicate with the GuC to obtain the GMDID value. Existing GuC functions that use this information assume that the GT has already set up its MMI...

Astra Linux – Vulnerability in Linux 5.10

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...

CVE-2024-36332

Improper isolation of GPU HW register space could allow a privileged attacker in malicious Guest Virtual Machine VM to perform unauthorized access to specific victim range of GPU MMIO register space, potentially causing the host OS to reboot and creating a Denial of Service DOS condition...

CVE-2025-61971

Missing lock bit protection for NBIO registers could allow a local admin-privileged attacker to modify MMIO routing configurations, potentially resulting in loss of SEV-SNP guest integrity...

CVE-2025-61971

Missing lock bit protection for NBIO registers could allow a local admin-privileged attacker to modify MMIO routing configurations, potentially resulting in loss of SEV-SNP guest integrity...

CVE-2025-61971

The CVE-2025-61971 entry concerns missing lock bit protection for NBIO registers in AMD systems, enabling a locally privileged attacker to modify MMIO routing configurations and potentially compromise SEV-SNP guest integrity. Connected sources confirm affected component as NBIO registers and MMIO...

AMD多款产品 安全漏洞

AMD EPYC is a high-performance server processor developed by American semiconductor company AMD. Several AMD products have security vulnerabilities.
