| Xen before 4.1.x, 4.2.x, and 4.3.x does not take the page_alloc_lock and grant_table.lock in the same order, which allows local guest administrators with access to multiple vcpus to cause a denial of service (host deadlock) via unspecified vectors. | |||||
| CVE-2011-1780 | 1 Xen | 1 Xen | 2025-04-11 | 6.1 MEDIUM | N/A |
| The instruction emulation in Xen 3.0.3 allows local SMP guest users to cause a denial of service (host crash) by replacing the instruction that causes the VM to exit in one thread with a different instruction in a different thread. | |||||
| CVE-2014-1950 | 1 Xen | 1 Xen | 2025-04-11 | 4.6 MEDIUM | N/A |
| Use-after-free vulnerability in the xc_cpupool_getinfo function in Xen 4.1.x through 4.3.x, when using a multithreaded toolstack, does not properly handle a failure by the xc_cpumap_alloc function, which allows local users with access to management functions to cause a denial of service (heap corruption) and possibly gain privileges via unspecified vectors. | |||||
| CVE-2012-4536 | 1 Xen | 1 Xen | 2025-04-11 | 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-2012-4411 | 1 Xen | 1 Xen | 2025-04-11 | 4.6 MEDIUM | N/A |
| The graphical console in Xen 4.0, 4.1 and 4.2 allows local OS guest administrators to obtain sensitive host resource information via the qemu monitor. NOTE: this might be a duplicate of CVE-2007-0998. | |||||
| CVE-2013-4356 | 1 Xen | 1 Xen | 2025-04-11 | 5.4 MEDIUM | N/A |
| Xen 4.3.x writes hypervisor mappings to certain shadow pagetables when live migration is performed on hosts with more than 5TB of RAM, which allows local 64-bit PV guests to read or write to invalid memory and cause a denial of service (crash). | |||||
