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-2012-6033 | 1 Xen | 1 Xen | 2024-08-06 | N/A |
| The do_tmem_control function in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 does not properly check privileges, which allows local guest OS users to access control stack operations via unspecified vectors. 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-2012-6035 | 1 Xen | 1 Xen | 2024-08-06 | N/A |
| The do_tmem_destroy_pool function in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 does not properly validate pool ids, which allows local guest OS users to cause a denial of service (memory corruption and host crash) or execute arbitrary code via unspecified vectors. 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-2012-6036 | 1 Xen | 1 Xen | 2024-08-06 | N/A |

| CVE-2012-5525 | 1 Xen | 1 Xen | 2024-08-06 | N/A |
| The get_page_from_gfn hypercall function in Xen 4.2 allows local PV guest OS administrators to cause a denial of service (crash) via a crafted GFN that triggers a buffer over-read. | ||||
