| CVE-2021-27803 | 3 Debian, Fedoraproject, W1.fi | 3 Debian Linux, Fedora, Wpa Supplicant | 2024-11-21 | 5.4 MEDIUM | 7.5 HIGH |
| A vulnerability was discovered in how p2p/p2p_pd.c in wpa_supplicant before 2.10 processes P2P (Wi-Fi Direct) provision discovery requests. It could result in denial of service or other impact (potentially execution of arbitrary code), for an attacker within radio range. | |||||
| CVE-2021-27645 | 3 Debian, Fedoraproject, Gnu | 3 Debian Linux, Fedora, Glibc | 2024-11-21 | 1.9 LOW | 2.5 LOW |
| The nameserver caching daemon (nscd) in the GNU C Library (aka glibc or libc6) 2.29 through 2.33, when processing a request for netgroup lookup, may crash due to a double-free, potentially resulting in degraded service or Denial of Service on the local system. This is related to netgroupcache.c. | |||||
| CVE-2021-27577 | 2 Apache, Debian | 2 Traffic Server, Debian Linux | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| Incorrect handling of url fragment vulnerability of Apache Traffic Server allows an attacker to poison the cache. This issue affects Apache Traffic Server 7.0.0 to 7.1.12, 8.0.0 to 8.1.1, 9.0.0 to 9.0.1. | |||||
| CVE-2021-27379 | 2 Debian, Xen | 2 Debian Linux, Xen | 2024-11-21 | 5.9 MEDIUM | 7.8 HIGH |
| An issue was discovered in Xen through 4.11.x, allowing x86 Intel HVM guest OS users to achieve unintended read/write DMA access, and possibly cause a denial of service (host OS crash) or gain privileges. This occurs because a backport missed a flush, and thus IOMMU updates were not always correct. NOTE: this issue exists because of an incomplete fix for CVE-2020-15565. | |||||
| 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. | |||||

| encoding.c in GNU Screen through 4.8.0 allows remote attackers to cause a denial of service (invalid write access and application crash) or possibly have unspecified other impact via a crafted UTF-8 character sequence. | |||||
| CVE-2021-26933 | 3 Debian, Fedoraproject, Xen | 3 Debian Linux, Fedora, Xen | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| An issue was discovered in Xen 4.9 through 4.14.x. On Arm, a guest is allowed to control whether memory accesses are bypassing the cache. This means that Xen needs to ensure that all writes (such as the ones during scrubbing) have reached the memory before handing over the page to a guest. Unfortunately, the operation to clean the cache is happening before checking if the page was scrubbed. Therefore there is no guarantee when all the writes will reach the memory. | |||||
| 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. | |||||
