In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Fix NULL domain on device release In the kdump kernel, the IOMMU operates in deferredattach mode. In this mode, info-domain may not yet be assigned by the time the releasedevice function is called. It leads to the...

CVE-2024-27079

CVE-2024-27079 affects the Linux kernel IAMMU VT-d code. Systems with kdump/crash kernel may crash due to NULL domain on device release in deferred_attach mode, triggering a NULL pointer dereference during device removal. The mitigated path uses the release_domain mechanism to clear the scalable ...
