IOMMU: RMRR (VT-d) and unity map (AMD-Vi) handling issues T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Certain PCI devices in a system might be assigned Reserved Memory Regions (specified via Reserved Memory Region Reporting, “RMRR”) for Intel VT-d or Unity Mapping ranges for AMD-Vi. These are typically used for platform tasks such as legacy USB emulation. Since the precise purpose of these regions is unknown, once a device associated with such a region is active, the mappings of these regions need to remain continuouly accessible by the device. This requirement has been violated. Subsequent DMA or interrupts from the device may have unpredictable behaviour, ranging from IOMMU faults to memory corruption.

x86 pv: Insufficient care with non-coherent mappings T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Xen maintains a type reference count for pages, in addition to a regular reference count. This scheme is used to maintain invariants required for Xen’s safety, e.g. PV guests may not have direct writeable access to pagetables; updates need auditing by Xen. Unfortunately, Xen’s safety logic doesn’t account for CPU-induced cache non-coherency; cases where the CPU can cause the content of the cache to be different to the content in main memory. In such cases, Xen’s safety logic can incorrectly conclude that the contents of a page is safe.

D-Link DIR-820L 1.05B03 was discovered to contain a remote command execution (RCE) vulnerability via the Device Name parameter in /lan.asp.

Suzuki Connect v1.0.15 allows attackers to tamper with displayed messages via spoofed CAN messages.

EyouCMS v1.5.4 was discovered to lack parameter filtering in usercontrollershop.php, leading to payment logic vulnerabilities.

Inappropriate implementation in Fullscreen API in Google Chrome on Android prior to 104.0.5112.79 allowed a remote attacker to spoof the contents of the Omnibox (URL bar) via a crafted HTML page.
