| CVE-2012-4544 | 1 Xen | 1 Xen | 2023-12-10 | 2.1 LOW | N/A |
| The PV domain builder in Xen 4.2 and earlier does not validate the size of the kernel or ramdisk (1) before or (2) after decompression, which allows local guest administrators to cause a denial of service (domain 0 memory consumption) via a crafted (a) kernel or (b) ramdisk. | |||||
| CVE-2013-4371 | 1 Xen | 1 Xen | 2023-12-10 | 4.4 MEDIUM | N/A |
| Use-after-free vulnerability in the libxl_list_cpupool function in the libxl toolstack library in Xen 4.2.x and 4.3.x, when running "under memory pressure," returns the original pointer when the realloc function fails, which allows local users to cause a denial of service (heap corruption and crash) and possibly execute arbitrary code via unspecified vectors. | |||||
| CVE-2013-4355 | 1 Xen | 1 Xen | 2023-12-10 | 1.5 LOW | N/A |
| Xen 4.3.x and earlier does not properly handle certain errors, which allows local HVM guests to obtain hypervisor stack memory via a (1) port or (2) memory mapped I/O write or (3) other unspecified operations related to addresses without associated memory. | |||||
| CVE-2012-6031 | 1 Xen | 1 Xen | 2023-12-10 | 4.7 MEDIUM | N/A |
| The do_tmem_get 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 (CPU hang and host crash) via unspecified vectors related to a spinlock being held in the "bad_copy 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-2012-3497 | 1 Xen | 1 Xen | 2023-12-10 | 6.9 MEDIUM | N/A |
| (1) TMEMC_SAVE_GET_CLIENT_WEIGHT, (2) TMEMC_SAVE_GET_CLIENT_CAP, (3) TMEMC_SAVE_GET_CLIENT_FLAGS and (4) TMEMC_SAVE_END 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 (NULL pointer dereference or memory corruption and host crash) or possibly have other unspecified impacts via a NULL client id. | |||||
| CVE-2013-2211 | 1 Xen | 1 Xen | 2023-12-10 | 7.4 HIGH | N/A |
| The libxenlight (libxl) toolstack library in Xen 4.0.x, 4.1.x, and 4.2.x uses weak permissions for xenstore keys for paravirtualised and emulated serial console devices, which allows local guest administrators to modify the xenstore value via unspecified vectors. | |||||

| The AMD IOMMU support in Xen 4.2.x, 4.1.x, 3.3, and other versions, when using AMD-Vi for PCI passthrough, uses the same interrupt remapping table for the host and all guests, which allows guests to cause a denial of service by injecting an interrupt into other guests. | |||||
| CVE-2013-4551 | 1 Xen | 1 Xen | 2023-12-10 | 5.7 MEDIUM | N/A |
