CVE-2026-68176 tracing: Fix mmiotrace possible NULL dereferencing of hiter->dev

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix mmiotrace possible NULL dereferencing of hiter-dev If the mmiopipeopen fails to find a PCI device, the hiter-dev will be assigned to NULL. The mmiotrace read function dereferences the hiter-dev if hiter exists. Chang...

CVE-2026-68176

The CVE-2026-68176 entry concerns the Linux kernel tracing subsystem (mmiotrace) where a NULL dereference could occur if mmio_pipe_open() fails to locate a PCI device and hiter->dev is NULL. The read() path previously dereferenced hiter->dev without verifying it; the fix adds a check for hi...

CVE-2026-64460

A flaw was found in the Linux kernel's PCI/IOV subsystem. When a PCI device fails to respond during a power state transition, the kernel's Virtual Function VF Resizable Base Address Register BAR restoration process can attempt to access memory outside of its allocated bounds. This out-of-bounds...
