Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: Networks: DSA: Felix: Fixed memory leak in felixsetupmmiofiltering. A memory leak can be avoided if no CPU port is defined. Addresses-Coverity-ID: 1492897 “Resource leak” Addresses-Coverity-ID: 1492899 “Resource leak”...

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 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 – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

A vulnerability was discovered in the Linux kernel before version 6.5.9. This vulnerability could be exploited by local users who have access to MMIO registers through the user space. Incorrect access checks in the VC handler, along with improper emulation of MMIO accesses using the SEV-ES...

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 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 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 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 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: 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...
