Xen PCI Passthrough Code Reading Back Hardware Registers DoS (XSA-337)

According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by a denial of service DoS vulnerability. Code paths in Xen's MSI handling have been identified which act on unsanitized values read back from device hardware registers. While devices strict...

Denial Of Service (DoS)

xen is vulnerable to denial of service DoS. The vulnerability exists as the PCI passthrough code improperly uses register data, causing code paths in Xen's MSI handling to act on unsanitized values read back from device hardware registers...

ALPINE-CVE-2020-25598

An issue was discovered in Xen 4.14.x. There is a missing unlock in the XENMEMacquireresource error path. The RCU Read, Copy, Update mechanism is a synchronisation primitive. A buggy error path in the XENMEMacquireresource exits without releasing an RCU reference, which is conceptually similar to...

CVE-2020-25601

An issue was discovered in Xen through 4.14.x. There is a lack of preemption in evtchnreset / evtchndestroy. In particular, the FIFO event channel model allows guests to have a large number of event channels active at a time. Closing all of these when resetting all event channels or when cleaning...
