In the Linux kernel, the following vulnerability has been resolved: xprtrdma: treat all calls not a bcall when bcserv is NULL When a rdma server returns a fault format reply, nfs v3 client may treats it as a bcall when bc service is not exist. The debug message at rpcrdmabcreceivecall are,...

UBUNTU-CVE-2021-47653

In the Linux kernel, the following vulnerability has been resolved: media: davinci: vpif: fix use-after-free on driver unbind The driver allocates and registers two platform device structures during probe, but the devices were never deregistered on driver unbind. This results in a use-after-free ...

CVE-2022-49568

CVE-2022-49568 affects the Linux kernel KVM code path, where a NULL dereference can occur during cleanup if destroy() is assumed non-NULL but is not (notably for some Book3s KVM devices that use release() instead). The root cause is an assumption in kvm_ioctl_create_device() that destroy() is alw...

CVE-2022-49568 KVM: Don't null dereference ops->destroy

In the Linux kernel, the following vulnerability has been resolved: KVM: Don't null dereference ops-destroy A KVM device cleanup happens in either of two callbacks: 1 destroy which is called when the VM is being destroyed; 2 release which is called when a device fd is closed. Most KVM devices use...

CVE-2022-49506

The CVE-2022-49506 issue affects the Linux kernel DRM/Mediatek path, where a race between the vblank callback registration and disabling vblank could yield NULL callback data in the ovl IRQ path, risking kernel panic. The documented fix adds a vblank callback registration flow: register callback ...

CVE-2022-49427 iommu/mediatek: Remove clk_disable in mtk_iommu_remove

In the Linux kernel, the following vulnerability has been resolved: iommu/mediatek: Remove clkdisable in mtkiommuremove After the commit b34ea31fe013 "iommu/mediatek: Always enable the clk on resume", the iommu clock is controlled by the runtime callback. thus remove the clk control in the...

CVE-2022-49427

The CVE pertains to the Linux kernel’s MTK IOMMU driver. After a patch (mtk_iommu_remove) removing clk_disable and relying on a runtime clock-control callback, the clock is now managed by runtime, eliminating the previous disable path. This addresses a warning trace seen when unbinding the MTK IO...
