| CVE-2012-6030 | 1 Xen | 1 Xen | 2017-08-28 | 7.2 HIGH | N/A |
| The do_tmem_op function in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 allow local guest OS users to cause a denial of service (host crash) and possibly have other unspecified impacts via unspecified vectors related to "broken locking checks" in an "error path." NOTE: this issue was originally published as part of CVE-2012-3497, which was too general; CVE-2012-3497 has been SPLIT into this ID and others. | |||||

| CVE-2012-4539 | 1 Xen | 1 Xen | 2017-08-28 | 2.1 LOW | N/A |
| Xen 4.0 through 4.2, when running 32-bit x86 PV guests on 64-bit hypervisors, allows local guest OS administrators to cause a denial of service (infinite loop and hang or crash) via invalid arguments to GNTTABOP_get_status_frames, aka "Grant table hypercall infinite loop DoS vulnerability." | |||||
| CVE-2012-4538 | 1 Xen | 1 Xen | 2017-08-28 | 4.9 MEDIUM | N/A |
| The HVMOP_pagetable_dying hypercall in Xen 4.0, 4.1, and 4.2 does not properly check the pagetable state when running on shadow pagetables, which allows a local HVM guest OS to cause a denial of service (hypervisor crash) via unspecified vectors. | |||||
| CVE-2012-4537 | 1 Xen | 1 Xen | 2017-08-28 | 2.1 LOW | N/A |
| Xen 3.4 through 4.2, and possibly earlier versions, does not properly synchronize the p2m and m2p tables when the set_p2m_entry function fails, which allows local HVM guest OS administrators to cause a denial of service (memory consumption and assertion failure), aka "Memory mapping failure DoS vulnerability." | |||||
| CVE-2012-4536 | 1 Xen | 1 Xen | 2017-08-28 | 2.1 LOW | N/A |
| The (1) domain_pirq_to_emuirq and (2) physdev_unmap_pirq functions in Xen 2.2 allows local guest OS administrators to cause a denial of service (Xen crash) via a crafted pirq value that triggers an out-of-bounds read. | |||||
| CVE-2012-4535 | 1 Xen | 1 Xen | 2017-08-28 | 1.9 LOW | N/A |
| Xen 3.4 through 4.2, and possibly earlier versions, allows local guest OS administrators to cause a denial of service (Xen infinite loop and physical CPU consumption) by setting a VCPU with an "inappropriate deadline." | |||||
