Denial Of Service (DoS)

kernel is vulnerable to denial of service. A flaw was found in the way the Xen hypervisor implementation handled instruction emulation during virtual machine exits. A malicious user-space process running in an SMP guest could trick the emulator into reading a different instruction than the one th...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS. The vulnerability exists as an off-by-one flaw was found in the addrok macro in the Linux kernel's Xen hypervisor implementation when running on 64-bit systems. A privileged guest user could trigger this flaw to cause the hypervisor to crash...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS. The vulnerability exists as a flaw was found in the way the Linux kernel's Xen hypervisor implementation emulated the SAHF instruction. When using a fully-virtualized guest on a host that does not use hardware assisted paging HAP, such as those runni...

Privilege Escalation

kernel is vulnerable to privilege escalation. The vulnerability exists as a flaw was found in the way the Xen hypervisor implementation checked for the upper boundary when getting a new event channel port. A privileged guest user could use this flaw to cause a denial of service or escalate their...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS. The vulnerability exists as a missing error checking in the way page tables were handled in the Xen hypervisor implementation could allow a privileged guest user to cause the host, and the guests, to lock up...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS. The vulnerability exists as a flaw was found in fixuppagefault in the Xen hypervisor implementation. If a 64-bit para-virtualized guest accessed a certain area of memory, it could cause a denial of service on the host system running the Xen hyperviso...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS. The vulnerability exists through a missing sanity check was found in vbdcreate in the Xen hypervisor implementation. As CD-ROM drives are not supported by the blkback back-end driver, attempting to use a virtual CD-ROM drive with blkback could trigge...

Denial Of Service (DoS)

kernel is vulnerable to denial of service. It was found that a malicious guest running on the Xen hypervisor could place invalid data in the memory that the guest shared with the blkback and blktap back-end drivers, resulting in a denial of service on the host system...

Denial Of Service (DoS)

kernel is vulnerable to denial of service. A flaw was found in the Xenbus code for the unified block-device I/O interface back end. A privileged guest user could use this flaw to cause a denial of service on the host system running the Xen hypervisor...

Denial Of Service (DoS)

kernel is vulnerable to denial of service. A flaw was found in the Xen hypervisor implementation when running a system that has an Intel CPU without Extended Page Tables EPT support. While attempting to dump information about a crashing fully-virtualized guest, the flaw could cause the hypervisor...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS. The vulnerability exists as a flaw was found in the Xen hypervisor implementation when using the Intel Itanium architecture, allowing guests to enter an unsupported state. An unprivileged guest user could trigger this flaw by setting the BE Big Endia...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS. The vulnerability exists as a flaw was found in the Memory-mapped I/O MMIO instruction decoder in the Xen hypervisor implementation. An unprivileged guest user could use this flaw to trick the hypervisor into emulating a certain instruction, which...

Xen Project Denial of Service (XSA-295)

According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by multiple denial of service DoS vulnerabilities : - A denial of service DoS vulnerability exists in the LoadExcl and StoreExcl operations due to a possible infinite loop. An unauthenticate...

Xen Information Disclosure Vulnerability (XSA-305)

According to its self-reported version number, the Xen Hypervisor installed on the remote host is affected by an information disclosure vulnerability. A TSX Asynchronous Abort condition exists on some CPUs utilizing speculative execution. An authenticated, local attacker can exploit this to...

Xen Device Quarantine for Alternate PCI Assignment Methods Privilege Escalation Vulnerability (XSA-306)

According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by a privilege escalation vulnerability due to an incomplete fix for CVE-2019-18424. An unauthenticated attacker with physical access to the device can exploit this issue, via an untrusted...

Xen Grant Table Transfer Issues on Large Hosts Denial of Service Vulnerability (XSA-284)

According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by a denial of service vulnerability. When the code processing grant table transfer requests finds a page with an address too large to be represented in the interface with the guest, it...

The vulnerability of the xenvif_set_hash_mapping function in Xen hypervisors allows a malicious actor to gain unauthorized access to information and compromise its integrity and accessibility.

The vulnerability of the xenvifsethashmapping function in Xen hypervisors is related to integer overflow when processing requests to the netback driver. Exploiting this vulnerability can allow an attacker to gain unauthorized access to information and compromise its integrity and availability...

The vulnerability of Xen hypervisors, related to improper error handling, allows a malicious actor to trigger a service failure.

The vulnerability of Xen hypervisors is related to incorrect error handling. Exploiting this vulnerability can allow an attacker to cause a service failure...

The vulnerability of Xen hypervisors arises from the improper accounting of resources by external emulators, allowing a malicious actor to trigger a service failure or increase their privileges.

The vulnerability of Xen hypervisors is related to the improper accounting of resources from external emulators. Exploiting this vulnerability can allow an attacker to cause service failures or increase their privileges...

The vulnerability of Xen hypervisors, related to the swapping of the zero pointer, allows a attacker to trigger a service failure.
