| Xen through 4.8.x on 64-bit platforms mishandles page tables after an IRET hypercall, which might allow PV guest OS users to execute arbitrary code on the host OS, aka XSA-213. | |||||
| CVE-2017-7995 | 3 Novell, Suse, Xen | 6 Suse Linux Enterprise Point Of Sale, Suse Linux Enterprise Server, Manager and 3 more | 2025-04-20 | 1.7 LOW | 3.8 LOW |
| Xen PV guest before Xen 4.3 checked access permissions to MMIO ranges only after accessing them, allowing host PCI device space memory reads, leading to information disclosure. This is an error in the get_user function. NOTE: the upstream Xen Project considers versions before 4.5.x to be EOL. | |||||
| CVE-2017-17565 | 1 Xen | 1 Xen | 2025-04-20 | 4.7 MEDIUM | 5.6 MEDIUM |
| An issue was discovered in Xen through 4.9.x allowing PV guest OS users to cause a denial of service (host OS crash) if shadow mode and log-dirty mode are in place, because of an incorrect assertion related to M2P. | |||||
| CVE-2017-17566 | 1 Xen | 1 Xen | 2025-04-20 | 6.9 MEDIUM | 7.8 HIGH |
| An issue was discovered in Xen through 4.9.x allowing PV guest OS users to cause a denial of service (host OS crash) or gain host OS privileges in shadow mode by mapping a certain auxiliary page. | |||||
| CVE-2016-9379 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | 4.6 MEDIUM | 7.9 HIGH |
| The pygrub boot loader emulator in Xen, when S-expression output format is requested, allows local pygrub-using guest OS administrators to read or delete arbitrary files on the host via string quotes and S-expressions in the bootloader configuration file. | |||||
| CVE-2017-15597 | 1 Xen | 1 Xen | 2025-04-20 | 9.0 HIGH | 9.1 CRITICAL |
| An issue was discovered in Xen through 4.9.x. Grant copying code made an implication that any grant pin would be accompanied by a suitable page reference. Other portions of code, however, did not match up with that assumption. When such a grant copy operation is being done on a grant of a dying domain, the assumption turns out wrong. A malicious guest administrator can cause hypervisor memory corruption, most likely resulting in host crash and a Denial of Service. Privilege escalation and information leaks cannot be ruled out. | |||||
| CVE-2017-14319 | 1 Xen | 1 Xen | 2025-04-20 | 7.2 HIGH | 8.8 HIGH |
| A grant unmapping issue was discovered in Xen through 4.9.x. When removing or replacing a grant mapping, the x86 PV specific path needs to make sure page table entries remain in sync with other accounting done. Although the identity of the page frame was validated correctly, neither the presence of the mapping nor page writability were taken into account. | |||||
| CVE-2017-15588 | 1 Xen | 1 Xen | 2025-04-20 | 6.9 MEDIUM | 7.8 HIGH |
| An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to execute arbitrary code on the host OS because of a race condition that can cause a stale TLB entry. | |||||
| CVE-2017-10922 | 1 Xen | 1 Xen | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
| The grant-table feature in Xen through 4.8.x mishandles MMIO region grant references, which allows guest OS users to cause a denial of service (loss of grant trackability), aka XSA-224 bug 3. | |||||
| CVE-2016-9380 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | 4.6 MEDIUM | 7.5 HIGH |
| The pygrub boot loader emulator in Xen, when nul-delimited output format is requested, allows local pygrub-using guest OS administrators to read or delete arbitrary files on the host via NUL bytes in the bootloader configuration file. | |||||
| CVE-2017-10920 | 1 Xen | 1 Xen | 2025-04-20 | 10.0 HIGH | 10.0 CRITICAL |
| The grant-table feature in Xen through 4.8.x mishandles a GNTMAP_device_map and GNTMAP_host_map mapping, when followed by only a GNTMAP_host_map unmapping, which allows guest OS users to cause a denial of service (count mismanagement and memory corruption) or obtain privileged host OS access, aka XSA-224 bug 1. | |||||
| CVE-2016-9818 | 1 Xen | 1 Xen | 2025-04-20 | 4.9 MEDIUM | 6.5 MEDIUM |
| Xen through 4.7.x allows local ARM guest OS users to cause a denial of service (host crash) via vectors involving an asynchronous abort while at HYP. | |||||
| CVE-2016-9932 | 1 Xen | 1 Xen | 2025-04-20 | 2.1 LOW | 3.3 LOW |
| CMPXCHG8B emulation in Xen 3.3.x through 4.7.x on x86 systems allows local HVM guest OS users to obtain sensitive information from host stack memory via a "supposedly-ignored" operand size prefix. | |||||
| CVE-2017-15589 | 1 Xen | 1 Xen | 2025-04-20 | 2.1 LOW | 6.5 MEDIUM |
| An issue was discovered in Xen through 4.9.x allowing x86 HVM guest OS users to obtain sensitive information from the host OS (or an arbitrary guest OS) because intercepted I/O operations can cause a write of data from uninitialized hypervisor stack memory. | |||||
| CVE-2017-15592 | 1 Xen | 1 Xen | 2025-04-20 | 7.2 HIGH | 8.8 HIGH |
| An issue was discovered in Xen through 4.9.x allowing x86 HVM guest OS users to cause a denial of service (hypervisor crash) or possibly gain privileges because self-linear shadow mappings are mishandled for translated guests. | |||||
| CVE-2017-12134 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | 7.2 HIGH | 8.8 HIGH |
| The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation. | |||||
| CVE-2016-9386 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | 4.6 MEDIUM | 7.8 HIGH |
| The x86 emulator in Xen does not properly treat x86 NULL segments as unusable when accessing memory, which might allow local HVM guest users to gain privileges via vectors involving "unexpected" base/limit values. | |||||
