| 2021-02-17 | 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... | Debian_linux, Fedora, Linux_kernel, Cloud_backup, Hci_compute_node, Hci_h410c_firmware, Solidfire\,_enterprise_sds_\&_hci_storage_node, Solidfire_\&_hci_management_node | 5.5 | ||
| 2021-02-17 | 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... | Debian_linux, Fedora, Linux_kernel | 7.8 | ||
| 2021-02-17 | 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... | Debian_linux, Fedora, Linux_kernel | 5.5 | ||
| 2021-03-05 | CVE-2021-28038 | 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. | Debian_linux, Linux_kernel, Cloud_backup, Solidfire_baseboard_management_controller_firmware | 6.5 | ||
| 2021-04-08 | CVE-2021-29154 | BPF JIT compilers in the Linux kernel through 5.11.12 have incorrect computation of branch displacements, allowing them to execute arbitrary code within the kernel context. This affects arch/x86/net/bpf_jit_comp.c and arch/x86/net/bpf_jit_comp32.c. | Debian_linux, Fedora, Linux_kernel, Cloud_backup, H300e_firmware, H300s_firmware, H410s_firmware, H500e_firmware, H500s_firmware, H700e_firmware, H700s_firmware, Hci_management_node, Solidfire | 7.8 | ||
| 2021-04-20 | CVE-2021-29155 | An issue was discovered in the Linux kernel through 5.11.x. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory. Specifically, for sequences of pointer arithmetic operations, the pointer modification performed by the first operation is not correctly accounted for when restricting subsequent operations. | Debian_linux, Fedora, Linux_kernel | 5.5 | ||
| 2021-06-14 | CVE-2021-34693 | net/can/bcm.c in the Linux kernel through 5.12.10 allows local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized. | Debian_linux, Linux_kernel | 5.5 | ||
| 2021-07-21 | CVE-2021-37159 | hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free. | Debian_linux, Linux_kernel, Communications_cloud_native_core_binding_support_function, Communications_cloud_native_core_network_exposure_function, Communications_cloud_native_core_policy | 6.4 | ||
| 2021-10-20 | CVE-2021-42739 | The firewire subsystem in the Linux kernel through 5.14.13 has a buffer overflow related to drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandles bounds checking. | Debian_linux, Fedora, Linux_kernel, Communications_cloud_native_core_binding_support_function, Communications_cloud_native_core_network_exposure_function, Communications_cloud_native_core_policy, Starwind_san_\&_nas, Starwind_virtual_san | 6.7 | ||
| 2021-11-17 | CVE-2021-43976 | In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic). | Debian_linux, Fedora, Linux_kernel, Cloud_backup, H300e_firmware, H300s_firmware, H410c_firmware, H410s_firmware, H500e_firmware, H500s_firmware, H700e_firmware, H700s_firmware, Communications_cloud_native_core_binding_support_function, Communications_cloud_native_core_network_exposure_function, Communications_cloud_native_core_policy | 4.6 |
