CVE-2023-54095

CVE-2023-54095 (Linux kernel) : The issue arises in powerpc/iommu where fail_iommu_setup() registers the same notifier_block on both PCI and VIO buses, turning the notifier_block into a shared linked list node. This can cause later notifiers for either bus to be registered on the other, triggerin...

CVE-2023-54095 powerpc/iommu: Fix notifiers being shared by PCI and VIO buses

In the Linux kernel, the following vulnerability has been resolved: powerpc/iommu: Fix notifiers being shared by PCI and VIO buses failiommusetup registers the failiommubusnotifier struct to both PCI and VIO buses. struct notifierblock is a linked list node, so this causes any notifiers later...

CVE-2022-50760

CVE-2022-50760 is a Linux kernel vulnerability affecting the DRM/AMDGPU path. The issue stems from a refcount handling in amdgpu_atrm_get_bios(): pci_get_class() returns a pci_device with an increased refcount, and when the loop is broken with a non-NULL pdev, the code must call pci_dev_put() to ...

CVE-2023-54013

CVE-2023-54013 concerns the Linux kernel where interconnect locking could deadlock between runpm and memory reclaim. The description notes a fix to decouple ICC locking by introducing a new icc_bw_lock to serialize bandwidth aggregation, separating it from paths that allocate memory (e.g., node/l...
