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 a security issue in vfio/pci, where a mask change to DisINTx via configuration space may compete with INTx...

CVE-2024-26745

In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries/iommu: IOMMU table is not initialized for kdump over SR-IOV When kdump kernel tries to copy dump data over SR-IOV, LPAR panics due to NULL pointer exception: Kernel attempted to read user page 0 - exploit attempt?...

DEBIAN-CVE-2024-26790

In the Linux kernel, the following vulnerability has been resolved: dmaengine: fsl-qdma: fix SoC may hang on 16 byte unaligned read There is chip ls1028a errata: The SoC may hang on 16 byte unaligned read transactions by QDMA. Unaligned read transactions initiated by QDMA may stall in the NOC...

CVE-2024-26745

CVE-2024-26745 pertains to the Linux kernel on pSeries POWER systems where the IOMMU table is not initialized for kdump over SR-IOV, causing a NULL pointer dereference when the kdump kernel initializes IOMMU/TCEs for SR-IOV devices. The root cause is IOMMU table initialization logic that only con...

CVE-2024-26738

A vulnerability was found in the Linux kernel, occurring during the Dynamic Logical Partitioning DLPAR add of a PCI device. The iommudevice structure is not properly initialized and this leads to a NULL pointer dereference which can cause kernel crashes...

CVE-2024-26762

In the Linux kernel, the following vulnerability has been resolved: cxl/pci: Skip to handle RAS errors if CXL.mem device is detached The PCI AER model is an awkward fit for CXL error handling. While the expectation is that a PCI device can escalate to link reset to recover from an AER event, the...

CVE-2024-26761

In the Linux kernel, the following vulnerability has been resolved: cxl/pci: Fix disabling memory if DVSEC CXL Range does not match a CFMWS window The Linux CXL subsystem is built on the assumption that HPA == SPA. That is, the host physical address HPA the HDM decoder registers are programmed wi...

DEBIAN-CVE-2024-26742

In the Linux kernel, the following vulnerability has been resolved: scsi: smartpqi: Fix disablemanagedinterrupts Correct blk-mq registration issue with module parameter disablemanagedinterrupts enabled. When we turn off the default PCIIRQAFFINITY flag, the driver needs to register with blk-mq usi...

CVE-2024-26738

In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries/iommu: DLPAR add doesn't completely initialize pcicontroller When a PCI device is dynamically added, the kernel oopses with a NULL pointer dereference: BUG: Kernel NULL pointer dereference on read at 0x00000030...

CVE-2024-26762

CVE-2024-26762 (Linux kernel) concerns CXL error handling. The fix addresses a crash: after unbinding the memory device (cxl_mem) following a RAS event, a later AER notification could access unmapped registers. The patch adds a check to verify memdev binding before reaping status register values,...
