| 2022-02-21 | CVE-2021-4115 | There is a flaw in polkit which can allow an unprivileged user to cause polkit to crash, due to process file descriptor exhaustion. The highest threat from this vulnerability is to availability. NOTE: Polkit process outage duration is tied to the failing process being reaped and a new one being spawned | Ubuntu_linux, Debian_linux, Fedora, Zfs_storage_appliance_kit, Polkit, Enterprise_linux | 5.5 | ||
| 2022-03-03 | CVE-2022-0492 | A vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly. | Ubuntu_linux, Debian_linux, Fedora, Linux_kernel, H300e, H300s, H410c, H410s, H500e, H500s, H700e, H700s, Hci_compute_node, Solidfire\,_enterprise_sds_\&_hci_storage_node, Solidfire_\&_hci_management_node, Codeready_linux_builder, Codeready_linux_builder_for_power_little_endian, Enterprise_linux, Enterprise_linux_eus, Enterprise_linux_for_ibm_z_systems, Enterprise_linux_for_ibm_z_systems_eus, Enterprise_linux_for_power_little_endian, Enterprise_linux_for_power_little_endian_eus, Enterprise_linux_for_real_time_for_nfv_tus, Enterprise_linux_for_real_time_tus, Enterprise_linux_server_aus, Enterprise_linux_server_for_power_little_endian_update_services_for_sap_solutions, Enterprise_linux_server_tus, Enterprise_linux_server_update_services_for_sap_solutions, Virtualization_host | 7.8 | ||
| 2022-03-03 | CVE-2021-3640 | A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del() together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A privileged local user could use this flaw to crash the system or escalate their privileges on the system. | Ubuntu_linux, Debian_linux, Fedora, Linux_kernel, H300e_firmware, H300s_firmware, H410c_firmware, H410s_firmware, H500e_firmware, H500s_firmware, H700e_firmware, H700s_firmware | 7.0 | ||
| 2022-03-04 | CVE-2021-3737 | A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop, consuming CPU time. The highest threat from this vulnerability is to system availability. | Ubuntu_linux, Fedora, Hci, Management_services_for_element_software, Netapp_xcp_smb, Ontap_select_deploy_administration_utility, Xcp_nfs, Communications_cloud_native_core_binding_support_function, Communications_cloud_native_core_network_exposure_function, Communications_cloud_native_core_policy, Python, Codeready_linux_builder, Codeready_linux_builder_for_ibm_z_systems, Codeready_linux_builder_for_power_little_endian, Enterprise_linux, Enterprise_linux_for_ibm_z_systems, Enterprise_linux_for_power_little_endian | 7.5 | ||
| 2022-03-23 | CVE-2021-3748 | A use-after-free vulnerability was found in the virtio-net device of QEMU. It could occur when the descriptor's address belongs to the non direct access region, due to num_buffers being set after the virtqueue elem has been unmapped. A malicious guest could use this flaw to crash QEMU, resulting in a denial of service condition, or potentially execute code on the host with the privileges of the QEMU process. | Ubuntu_linux, Debian_linux, Fedora, Qemu, Enterprise_linux, Enterprise_linux_advanced_virtualization_eus | 7.5 | ||
| 2022-03-29 | CVE-2022-1055 | A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 | Ubuntu_linux, Fedora, Linux_kernel, H300e_firmware, H300s_firmware, H410c_firmware, H410s_firmware, H500e_firmware, H500s_firmware, H700e_firmware, H700s_firmware, Enterprise_linux | 7.8 | ||
| 2022-05-17 | CVE-2022-29581 | Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14 and later versions. | Ubuntu_linux, Debian_linux, Linux_kernel, H300e_firmware, H300s_firmware, H410c_firmware, H410s_firmware, H500e_firmware, H500s_firmware, H700e_firmware, H700s_firmware | 7.8 | ||
| 2022-07-04 | CVE-2022-34918 | An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c. | Ubuntu_linux, Debian_linux, Linux_kernel, H300s_firmware, H410c_firmware, H410s_firmware, H500s_firmware, H700s_firmware | 7.8 | ||
| 2022-08-23 | CVE-2021-3905 | A memory leak was found in Open vSwitch (OVS) during userspace IP fragmentation processing. An attacker could use this flaw to potentially exhaust available memory by keeping sending packet fragments. | Ubuntu_linux, Fedora, Openvswitch, Enterprise_linux_fast_datapath | 7.5 | ||
| 2022-08-23 | CVE-2021-3975 | A use-after-free flaw was found in libvirt. The qemuMonitorUnregister() function in qemuProcessHandleMonitorEOF is called using multiple threads without being adequately protected by a monitor lock. This flaw could be triggered by the virConnectGetAllDomainStats API when the guest is shutting down. An unprivileged client with a read-only connection could use this flaw to perform a denial of service attack by causing the libvirt daemon to crash. | Ubuntu_linux, Debian_linux, Fedora, Ontap_select_deploy_administration_utility, Codeready_linux_builder, Enterprise_linux, Enterprise_linux_eus, Enterprise_linux_for_ibm_z_systems, Enterprise_linux_for_ibm_z_systems_eus, Enterprise_linux_for_power_little_endian, Enterprise_linux_for_power_little_endian_eus, Enterprise_linux_server_for_power_little_endian_update_services_for_sap_solutions, Enterprise_linux_server_tus, Libvirt | 6.5 |
