| CVE-2021-28039 | 3 Linux, Netapp, Xen | 4 Linux Kernel, Cloud Backup, Solidfire Baseboard Management Controller Firmware and 1 more | 2024-11-21 | 2.1 LOW | 6.5 MEDIUM |
| An issue was discovered in the Linux kernel 5.9.x through 5.11.3, as used with Xen. In some less-common configurations, an x86 PV guest OS user can crash a Dom0 or driver domain via a large amount of I/O activity. The issue relates to misuse of guest physical addresses when a configuration has CONFIG_XEN_UNPOPULATED_ALLOC but not CONFIG_XEN_BALLOON_MEMORY_HOTPLUG. | |||||
| CVE-2021-28038 | 3 Debian, Linux, Netapp | 4 Debian Linux, Linux Kernel, Cloud Backup and 1 more | 2024-11-21 | 4.9 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in the Linux kernel through 5.11.3, as used with Xen PV. A certain part of the netback driver lacks necessary treatment of errors such as failed memory allocations (as a result of changes to the handling of grant mapping errors). A host OS denial of service may occur during misbehavior of a networking frontend driver. NOTE: this issue exists because of an incomplete fix for CVE-2021-26931. | |||||
| CVE-2021-27365 | 4 Debian, Linux, Netapp and 1 more | 5 Debian Linux, Linux Kernel, Solidfire Baseboard Management Controller and 2 more | 2024-11-21 | 4.6 MEDIUM | 7.8 HIGH |
| An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have appropriate length constraints or checks, and can exceed the PAGE_SIZE value. An unprivileged user can send a Netlink message that is associated with iSCSI, and has a length up to the maximum length of a Netlink message. | |||||
| CVE-2021-27364 | 5 Canonical, Debian, Linux and 2 more | 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more | 2024-11-21 | 3.6 LOW | 7.1 HIGH |
| An issue was discovered in the Linux kernel through 5.11.3. drivers/scsi/scsi_transport_iscsi.c is adversely affected by the ability of an unprivileged user to craft Netlink messages. | |||||
| CVE-2021-27363 | 3 Debian, Linux, Netapp | 4 Debian Linux, Linux Kernel, Cloud Backup and 1 more | 2024-11-21 | 3.6 LOW | 4.4 MEDIUM |
| An issue was discovered in the Linux kernel through 5.11.3. A kernel pointer leak can be used to determine the address of the iscsi_transport structure. When an iSCSI transport is registered with the iSCSI subsystem, the transport's handle is available to unprivileged users via the sysfs file system, at /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When read, the show_transport_handle function (in drivers/scsi/scsi_transport_iscsi.c) is called, which leaks the handle. This handle is actually the pointer to an iscsi_transport struct in the kernel module's global variables. | |||||
| CVE-2021-26934 | 2 Fedoraproject, Linux | 2 Fedora, Linux Kernel | 2024-11-21 | 4.6 MEDIUM | 7.8 HIGH |
| An issue was discovered in the Linux kernel 4.18 through 5.10.16, as used by Xen. The backend allocation (aka be-alloc) mode of the drm_xen_front drivers was not meant to be a supported configuration, but this wasn't stated accordingly in its support status entry. | |||||
| CVE-2021-26932 | 4 Debian, Fedoraproject, Linux and 1 more | 9 Debian Linux, Fedora, Linux Kernel and 6 more | 2024-11-21 | 1.9 LOW | 5.5 MEDIUM |
| An issue was discovered in the Linux kernel 3.2 through 5.10.16, as used by Xen. Grant mapping operations often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success or failure of each one is reported to the backend driver, and the backend driver then loops over the results, performing follow-up actions based on the success or failure of each operation. Unfortunately, when running in PV mode, the Linux backend drivers mishandle this: Some errors are ignored, effectively implying their success from the success of related batch elements. In other cases, errors resulting from one batch element lead to further batch elements not being inspected, and hence successful ones to not be possible to properly unmap upon error recovery. Only systems with Linux backends running in PV mode are vulnerable. Linux backends run in HVM / PVH modes are not vulnerable. This affects arch/*/xen/p2m.c and drivers/xen/gntdev.c. | |||||
| CVE-2021-26931 | 3 Debian, Fedoraproject, Linux | 3 Debian Linux, Fedora, Linux Kernel | 2024-11-21 | 1.9 LOW | 5.5 MEDIUM |
| An issue was discovered in the Linux kernel 2.6.39 through 5.10.16, as used in Xen. Block, net, and SCSI backends consider certain errors a plain bug, deliberately causing a kernel crash. For errors potentially being at least under the influence of guests (such as out of memory conditions), it isn't correct to assume a plain bug. Memory allocations potentially causing such crashes occur only when Linux is running in PV mode, though. This affects drivers/block/xen-blkback/blkback.c and drivers/xen/xen-scsiback.c. | |||||
| CVE-2021-26930 | 3 Debian, Fedoraproject, Linux | 3 Debian Linux, Fedora, Linux Kernel | 2024-11-21 | 4.6 MEDIUM | 7.8 HIGH |
| An issue was discovered in the Linux kernel 3.11 through 5.10.16, as used by Xen. To service requests to the PV backend, the driver maps grant references provided by the frontend. In this process, errors may be encountered. In one case, an error encountered earlier might be discarded by later processing, resulting in the caller assuming successful mapping, and hence subsequent operations trying to access space that wasn't mapped. In another case, internal state would be insufficiently updated, preventing safe recovery from the error. This affects drivers/block/xen-blkback/blkback.c. | |||||
| CVE-2021-26708 | 2 Linux, Netapp | 12 Linux Kernel, 500f, A250 and 9 more | 2024-11-21 | 6.9 MEDIUM | 7.0 HIGH |
| A local privilege escalation was discovered in the Linux kernel before 5.10.13. Multiple race conditions in the AF_VSOCK implementation are caused by wrong locking in net/vmw_vsock/af_vsock.c. The race conditions were implicitly introduced in the commits that added VSOCK multi-transport support. | |||||
| CVE-2021-26639 | 2 Linux, Wisa | 2 Linux Kernel, Smart Wing Cms | 2024-11-21 | N/A | 8.1 HIGH |

| CVE-2021-26628 | 2 Linux, Maxb | 2 Linux Kernel, Maxboard | 2024-11-21 | 4.3 MEDIUM | 8.1 HIGH |
| Insufficient script validation of the admin page enables XSS, which causes unauthorized users to steal admin privileges. When uploading file in a specific menu, the verification of the files is insufficient. It allows remote attackers to upload arbitrary files disguising them as image files. | |||||
