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...

UBUNTU-CVE-2021-47147

In the Linux kernel, the following vulnerability has been resolved: ptp: ocp: Fix a resource leak in an error handling path If an error occurs after a successful 'pciioremapbar' call, it must be undone by a corresponding 'pciiounmap' call, as already done in the remove function...

ALPINE-CVE-2023-46839

PCI devices can make use of a functionality called phantom functions, that when enabled allows the device to generate requests using the IDs of functions that are otherwise unpopulated. This allows a device to extend the number of outstanding requests. Such phantom functions need an IOMMU context...

CVE-2021-46909

In the Linux kernel, the following vulnerability has been resolved: ARM: footbridge: fix PCI interrupt mapping Since commit 30fdfb929e82 "PCI: Add a call to pciassignirq in pcideviceprobe", the PCI code will call the IRQ mapping function whenever a PCI driver is probed. If these are marked as ini...

Linux kernel security vulnerabilities

The Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. A security vulnerability exists in the Linux kernel that stems from PCI code calling IRQ mapping functions whenever the PCI driver is probed. If these are flagged as init, this can lead to a...

kernel: EDAC/i10nm: fix refcount leak in pci_get_dev_wrapper()

In the Linux kernel, the following vulnerability has been resolved: EDAC/i10nm: fix refcount leak in pcigetdevwrapper As the comment of pcigetdomainbusandslot says, it returns a PCI device with refcount incremented, so it doesn't need to call an extra pcidevget in pcigetdevwrapper, and the PCI...

kernel: iommu/amd: Fix pci device refcount leak in ppr_notifier()

A reference counting violation was found in the Linux kernel's AMD IOMMU PPR Peripheral Page Request notification handler. When the handler looks up PCI devices using pcigetdomainbusandslot, it receives a reference-counted device pointer but never releases that reference before returning. This...

kernel: PCI: Fix dropping valid root bus resources with .end = zero

In the Linux kernel, the following vulnerability has been resolved: PCI: Fix dropping valid root bus resources with .end = zero On r8a7791/koelsch: kmemleak: 1 new suspected memory leaks see /sys/kernel/debug/kmemleak cat /sys/kernel/debug/kmemleak unreferenced object 0xc3a34e00 size 64: comm...

kernel: PCI: Fix use-after-free in pci_bus_release_domain_nr()

A use-after-free exists in the linux kernel such that The kernel frees the struct pcibus in pciremovebus via releasepcibusdev. After the structure is freed, a callback pcibusreleasedomainnr accesses that freed memory, leading to damage to system availability...

kernel: Linux kernel: Denial of Service due to PCI device reference count leak

A flaw was found in the Linux kernel. A local low-privileged user could exploit a reference count leak in the drm/amdgpu component. This vulnerability, related to how PCI Peripheral Component Interconnect devices are managed, could lead to a Denial of Service DoS by exhausting system resources...

OESA-2023-1655 qemu security update

QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. Security Fixes: hw/pci/pci.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access by providing an address near the end of the PCI configuration space.CVE-2020-13791 An issue was...

kernel: perf/x86/intel/uncore: Fix reference count leak in hswep_has_limit_sbox()

In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel/uncore: Fix reference count leak in hswephaslimitsbox pcigetdevice will increase the reference count for the returned 'dev'. We need to call pcidevput to decrease the reference count. Since 'dev' is only used in...

kernel: perf/x86/intel/uncore: Fix reference count leak in snr_uncore_mmio_map()

In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel/uncore: Fix reference count leak in snruncoremmiomap pcigetdevice will increase the reference count for the returned pcidev, so snruncoregetmcdev will return a pcidev with its reference count increased. We need to...

SUSE CVE-2011-4347

The kvmvmioctlassigndevice function in virt/kvm/assigned-dev.c in the KVM subsystem in the Linux kernel before 3.1.10 does not verify permission to access PCI configuration space and BAR resources, which allows host OS users to assign PCI devices and cause a denial of service host OS crash via a...

SUSE CVE-2013-3495

The Intel VT-d Interrupt Remapping engine in Xen 3.3.x through 4.3.x allows local guests to cause a denial of service kernel panic via a malformed Message Signaled Interrupt MSI from a PCI device that is bus mastering capable that triggers a System Error Reporting SERR Non-Maskable Interrupt NMI...

SUSE CVE-2019-19057

Two memory leaks in the mwifiexpcieinitevtring function in drivers/net/wireless/marvell/mwifiex/pcie.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service memory consumption by triggering mwifiexmappcimemory failures, aka CID-d10dcb615c8e...

SUSE CVE-2019-19579

An issue was discovered in Xen through 4.12.x allowing attackers to gain host OS privileges via DMA in a situation where an untrusted domain has access to a physical device and assignable-add is not used, because of an incomplete fix for CVE-2019-18424. XSA-302 relies on the use of libxl's...
