CVE-2025-68760 iommu/amd: Fix potential out-of-bounds read in iommu_mmio_show

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Fix potential out-of-bounds read in iommummioshow In iommummiowrite, it validates the user-provided offset with the check: iommu-dbgmmiooffset iommu-mmiophysend - 4. This assumes a 4-byte access. However, the...

CVE-2025-68760

The CVE-2025-68760 entry concerns a Linux kernel vulnerability in the AMD IOMMU where iommu_mmio_write() validates the user offset against mmio_phys_end - 4 (assuming 4-byte access), but iommu_mmio_show() performs an 8-byte read (readq). If the offset equals mmio_phys_end - 4, this allows a 4-byt...

CVE-2023-54024

The CVE-2023-54024 issue affects the Linux kernel’s KVM coalesced MMIO path. If the kernel’s kvm_io_bus_unregister_dev() removal fails, the code now destroys and frees the target coalesced MMIO device to avoid an unreferenced memory leak and inconsistent state. The provided description notes that...

CVE-2023-54024 KVM: Destroy target device if coalesced MMIO unregistration fails

In the Linux kernel, the following vulnerability has been resolved: KVM: Destroy target device if coalesced MMIO unregistration fails Destroy and free the target coalesced MMIO device if unregistering said device fails. As clearly noted in the code, kvmiobusunregisterdev does not destroy the targ...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the failure to destroy the target device when the KVM merge MMIO device logout fails, potentially leading to...

CAPIO: Safe Kernel-Bypass of Commodity Devices Using Capabilities

Securing low-latency I/O in commodity systems forces a fundamental trade-off: rely on the kernel's high overhead mediated interface, or bypass it entirely, exposing sensitive hardware resources to userspace and creating new vulnerabilities. This dilemma stems from a hardware granularity mismatch:...

CVE-2022-50615

CVE-2022-50615 affects the Linux kernel’s perf/x86/intel/uncore code. The root cause is a reference-count leak in snr_uncore_mmio_map() where pci_get_device() increases the pci_dev reference count and snr_uncore_get_mc_dev() returns a pci_dev with an extra reference. The fix is to call pci_dev_pu...

winbond_spinand_table Structure Memory Map DoS

The vulnerability of the “winbondspinandtable” structure definition in the drivers/mtd/nand/spi/winbond.c module – Linux’s memory driver support mechanism – is related to a violation of the buffer boundary. Exploiting this vulnerability could allow an attacker to cause a system failure...
