Qualcomm Chipsets are a family of chipsets from Qualcomm Incorporated USA. A resource management error vulnerability exists in Qualcomm Chipsets, which arises from memory corruption that occurs when simultaneously processing memory-mapped or unmapped IOCTL operations...

SUSE CVE-2024-57999

In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries/iommu: IOMMU incorrectly marks MMIO range in DDW Power Hypervisor can possibily allocate MMIO window intersecting with Dynamic DMA Window DDW range, which is over 32-bit addressing. These MMIO pages needs to be...

DEBIAN-CVE-2022-49665

In the Linux kernel, the following vulnerability has been resolved: platform/x86: thinkpadacpi: Fix a memory leak of EFCH MMIO resource Unlike releasememregion, a call to releaseresource does not free the resource, so it has to be freed explicitly to avoid a memory leak...

CVE-2022-49653 i2c: piix4: Fix a memory leak in the EFCH MMIO support

In the Linux kernel, the following vulnerability has been resolved: i2c: piix4: Fix a memory leak in the EFCH MMIO support The recently added support for EFCH MMIO regions introduced a memory leak in that code path. The leak is caused by the fact that releaseresource merely removes the resource...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: x86/tdx: Fixed the “in-kernel MMIO” check TDX only supports MMIO operations initiated by the kernel. The handlemmio function checks whether the VE exception occurred in the kernel and rejects the operation if it did. However,...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: x86/tdx: Fixed a data leak in the mmioread function. The mmioread function calls a TDVMCALL to retrieve MMIO data for a given address from the VMM. Sean noticed that mmioread inadvertently exposes the value of an initialized...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Do not allow mapping the MMIO HDP page with large pages. In that case, we do not receive the correct offset. The GPU has an unused 4K area of the register BAR space, into which we can remap registers. We remap the HDP...

UBUNTU-CVE-2024-56689

In the Linux kernel, the following vulnerability has been resolved: PCI: endpoint: epf-mhi: Avoid NULL dereference if DT lacks 'mmio' If platformgetresourcebyname fails and returns NULL because DT lacks an 'mmio' property for the MHI endpoint, dereferencing res-start will cause a NULL pointer...

SUSE CVE-2024-53196

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Don't retire aborted MMIO instruction Returning an abort to the guest for an unsupported MMIO access is a documented feature of the KVM UAPI. Nevertheless, it's clear that this plumbing has seen limited testing, since...

SUSE CVE-2024-45818

The hypervisor contains code to accelerate VGA memory accesses for HVM guests, when the virtual VGA is in "standard" mode. Locking involved there has an unusual discipline, leaving a lock acquired past the return from the function that acquired it. This behavior results in a problem when emulatin...
