| CVE-2019-17341 | 1 Xen | 1 Xen | 2024-11-21 | 6.9 MEDIUM | 7.8 HIGH |
| An issue was discovered in Xen through 4.11.x allowing x86 PV guest OS users to cause a denial of service or gain privileges by leveraging a page-writability race condition during addition of a passed-through PCI device. | |||||
| CVE-2019-17340 | 2 Debian, Xen | 2 Debian Linux, Xen | 2024-11-21 | 6.1 MEDIUM | 8.8 HIGH |
| An issue was discovered in Xen through 4.11.x allowing x86 guest OS users to cause a denial of service or gain privileges because grant-table transfer requests are mishandled. | |||||
| CVE-2018-8897 | 8 Apple, Canonical, Citrix and 5 more | 11 Mac Os X, Ubuntu Linux, Xenserver and 8 more | 2024-11-21 | 7.2 HIGH | 7.8 HIGH |
| A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer's Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. The MOV to SS and POP SS instructions inhibit interrupts (including NMIs), data breakpoints, and single step trap exceptions until the instruction boundary following the next instruction (SDM Vol. 3A; section 6.8.3). (The inhibited data breakpoints are those on memory accessed by the MOV to SS or POP to SS instruction itself.) Note that debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF) system flag (SDM Vol. 3A; section 2.3). If the instruction following the MOV to SS or POP to SS instruction is an instruction like SYSCALL, SYSENTER, INT 3, etc. that transfers control to the operating system at CPL < 3, the debug exception is delivered after the transfer to CPL < 3 is complete. OS kernels may not expect this order of events and may therefore experience unexpected behavior when it occurs. | |||||
| CVE-2018-7542 | 2 Debian, Xen | 2 Debian Linux, Xen | 2024-11-21 | 4.9 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Xen 4.8.x through 4.10.x allowing x86 PVH guest OS users to cause a denial of service (NULL pointer dereference and hypervisor crash) by leveraging the mishandling of configurations that lack a Local APIC. | |||||
| CVE-2018-7541 | 2 Debian, Xen | 2 Debian Linux, Xen | 2024-11-21 | 6.1 MEDIUM | 8.8 HIGH |
| An issue was discovered in Xen through 4.10.x allowing guest OS users to cause a denial of service (hypervisor crash) or gain privileges by triggering a grant-table transition from v2 to v1. | |||||
| CVE-2018-7540 | 2 Debian, Xen | 2 Debian Linux, Xen | 2024-11-21 | 4.9 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Xen through 4.10.x allowing x86 PV guest OS users to cause a denial of service (host OS CPU hang) via non-preemptable L3/L4 pagetable freeing. | |||||
| CVE-2018-5244 | 1 Xen | 1 Xen | 2024-11-21 | 4.9 MEDIUM | 6.5 MEDIUM |
| In Xen 4.10, new infrastructure was introduced as part of an overhaul to how MSR emulation happens for guests. Unfortunately, one tracking structure isn't freed when a vcpu is destroyed. This allows guest OS administrators to cause a denial of service (host OS memory consumption) by rebooting many times. | |||||
| CVE-2018-19967 | 2 Debian, Xen | 2 Debian Linux, Xen | 2024-11-21 | 4.9 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Xen through 4.11.x on Intel x86 platforms allowing guest OS users to cause a denial of service (host OS hang) because Xen does not work around Intel's mishandling of certain HLE transactions associated with the KACQUIRE instruction prefix. | |||||
| CVE-2018-19966 | 2 Debian, Xen | 2 Debian Linux, Xen | 2024-11-21 | 7.2 HIGH | 8.8 HIGH |
| An issue was discovered in Xen through 4.11.x allowing x86 PV guest OS users to cause a denial of service (host OS crash) or possibly gain host OS privileges because of an interpretation conflict for a union data structure associated with shadow paging. NOTE: this issue exists because of an incorrect fix for CVE-2017-15595. | |||||
| CVE-2018-19965 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2024-11-21 | 4.7 MEDIUM | 5.6 MEDIUM |
| An issue was discovered in Xen through 4.11.x allowing 64-bit PV guest OS users to cause a denial of service (host OS crash) because #GP[0] can occur after a non-canonical address is passed to the TLB flushing code. NOTE: this issue exists because of an incorrect CVE-2017-5754 (aka Meltdown) mitigation. | |||||
| CVE-2018-19964 | 1 Xen | 1 Xen | 2024-11-21 | 4.9 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Xen 4.11.x allowing x86 guest OS users to cause a denial of service (host OS hang) because the p2m lock remains unavailable indefinitely in certain error conditions. | |||||
