SUSE CVE-2019-18420
An issue was discovered in Xen through 4.12.x allowing x86 PV guest OS users to cause a denial of service via a VCPUOPinitialise hypercall. hypercallcreatecontinuation is a variadic function which uses a printf-like format string to interpret its parameters. Error handling for a bad format...
Denial Of Service (DoS)
xen is vulnerable to denial of service. The vulnerability exists due to an insufficient TLB flush for x86 PV guests in shadow mode which allows an attacker to crash the application by providing a malicious input...

grant table v2 status pages may remain accessible after de-allocation
ISSUE DESCRIPTION Guest get permitted access to certain Xen-owned pages of memory. The majority of such pages remain allocated / associated with a guest for its entire lifetime. Grant table v2 status pages, however, get de-allocated when a guest switched back from v2 to v1. The freeing of such...

CVE-2020-25599
An issue was discovered in Xen through 4.14.x. There are evtchnreset race conditions. Uses of EVTCHNOPreset potentially by a guest on itself or XENDOMCTLsoftreset by itself covered by XSA-77 can lead to the violation of various internal assumptions. This may lead to out of bounds memory accesses ...
races with evtchn_reset()
ISSUE DESCRIPTION Uses of EVTCHNOPreset potentially by a guest on itself or XENDOMCTLsoftreset by itself covered by XSA-77 can lead to the violation of various internal assumptions. This may lead to out of bounds memory accesses or triggering of bug checks. IMPACT In particular x86 PV guests may ...
x86 pv: Crash when handling guest access to MSR_MISC_ENABLE
ISSUE DESCRIPTION When a guest accesses certain Model Specific Registers, Xen first reads the value from hardware to use as the basis for auditing the guest access. For the MISCENABLE MSR, which is an Intel specific MSR, this MSR read is performed without error handling for a GP fault, which is t...
