kernel: Linux kernel: Denial of Service due to race condition in IOMMU pasid unbinding

A flaw was found in the Linux kernel's iommu/amd/iommuv2 component. A local attacker with low privileges could exploit a race condition during pasid unbinding when outstanding page faults exist. This vulnerability causes a reference count to incorrectly decrement to zero, leading to a memory leak...

CVE-2024-27067

The CVE-2024-27067 issue is in the Linux kernel (xen/evtchn) where unbinding a user event channel could cause a WARN() in the handler if the kernel is built with CONFIG_DEBUG_SHIRQ. The fix adds an "unbinding" flag to struct user_event to short-circuit the handler, preventing the WARN() when unbi...
