CVE-2026-46022

CVE-2026-46022 relates to the Linux kernel code in misc: ibmasm where an OOB MMIO read occurs in ibmasm_handle_mouse_interrupt due to unbounded queue index usage. The root cause is unbounded values from get_queue_reader()/get_queue_writer() fed into get_queue_entry(), producing a potentially inva...

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 7.0.11-1.1 Description An out-of-bounds MMIO Memory Mapped I/O read exists in the ibmasm handle mouse interrupt function. This occurs when the queue reader or writer index from the hardware exceeds REMOTE QUEUE...

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 – 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 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: Wifi: mt76: connac: Do not check WED status for non-MMIO devices WED is only supported for MMIO devices. Therefore, do not check it for USB or SDIO devices. This patch fixes the crash reported below: 21.946627 wlp0s3u1i3:...

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...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: Platform/x86: thinkpadacpi – Fixed a memory leak related to the EFCH MMIO resource.

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 – 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...
