Name of the Vulnerable Software and Affected Versions: Linux kernel version 6.7.0-203405+ Description: The Linux kernel has a vulnerability that causes a NULL pointer dereference when a PCI device is dynamically added. This occurs because the iommu device structure is not properly initialized...

CVE-2024-26650

REJECTED CVE A deadlock issue was identified in the Linux kernel within the platform/x86 P2SB subsystem. The issue arises when the p2sbbar function, used to unhide the P2SB device for resource retrieval, locks pcirescanremovelock during PCI device probing. If a PCI bus rescan is triggered e.g., v...

CVE-2023-52617

In the Linux kernel, the following vulnerability has been resolved: PCI: switchtec: Fix stdevrelease crash after surprise hot remove A PCI device hot removal may occur while stdev-cdev is held open. The call to stdevrelease then happens during close or exit, at a point way past switchtecpciremove...

CVE-2023-52617

CVE-2023-52617 : Linux kernel PCI: switchtec device crash on surprise hot-remove fixed. The issue occurred when a PCI device was hot-removed while stdev->cdev was open; stdev_release() ran after switchtec_pci_remove(), risking a fatal page fault in DMA mode and a stale dev pointer during dma_f...

kernel: mt76: mt7915: Fix PCI device refcount leak in mt7915_pci_init_hif2()

In the Linux kernel, the following vulnerability has been resolved: mt76: mt7915: Fix PCI device refcount leak in mt7915pciinithif2 As comment of pcigetdevice says, it returns a pcidevice with its refcount increased. We need to call pcidevput to decrease the refcount. Save the return value of...

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: Linux kernel: Resource exhaustion in amdgpu due to PCI device reference count leak

A flaw was found in the Linux kernel's drm/amdgpu component. A missing call to pcidevput in the amdgpuatrmgetbios function leads to a PCI device reference count leak. A local attacker could exploit this to cause resource exhaustion, potentially resulting in a Denial of Service DoS...

Denial Of Service (DoS)

libvirt is vulnerable to Denial of service . This security flaw occurs due to repeatedly querying an SR-IOV PCI device's capabilities that exposes a memory leak caused by a failure to free the virPCIVirtualFunction array within the parent struct's gautoptr cleanup...

USN-6397-1: Linux kernel (BlueField) vulnerabilities

Daniel Moghimi discovered that some IntelR Processors did not properly clear microarchitectural state after speculative execution of various instructions. A local unprivileged user could use this to obtain to sensitive information. CVE-2022-40982 Ruihan Li discovered that the bluetooth subsystem ...
