"Description": "This update upgrades kernel-image-un-def to version 5.10.17-alt1. \nSecurity Fix(es):\n\n * BDU:2021-02594: Уязвимость компонента drivers/block/xen-blkback/blkback.c ядра операционных систем Linux, позволяющая нарушителю оказать воздействие на конфиденциальность, целостность и доступность защищаемой информации\n\n * BDU:2021-02595: Уязвимость компонентов arch/*/xen/p2m.c, drivers/xen/gntdev.c ядра операционных систем Linux, позволяющая нарушителю вызвать отказ в обслуживании\n\n * BDU:2021-02597: Уязвимость драйверов drm_xen_front ядра операционной системы Linux, позволяющая нарушителю выполнить произвольный код\n\n * BDU:2021-02733: Уязвимость драйверов drivers/block/xen-blkback/blkback.c, drivers/xen/xen-scsiback.c ядра операционной системы Linux, позволяющая нарушителю вызвать отказ в обслуживании\n\n * CVE-2021-26930: 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.\n\n * CVE-2021-26931: 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.\n\n * CVE-2021-26932: 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.\n\n * CVE-2021-26934: 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.",
