| 2022-02-17 | CVE-2021-44731 | A race condition existed in the snapd 2.54.2 snap-confine binary when preparing a private mount namespace for a snap. This could allow a local attacker to gain root privileges by bind-mounting their own contents inside the snap's private mount namespace and causing snap-confine to execute arbitrary code and hence gain privilege escalation. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1 | Snapd, Ubuntu_linux, Debian_linux, Fedora | 7.8 | ||
| 2022-02-17 | CVE-2021-4120 | snapd 2.54.2 fails to perform sufficient validation of snap content interface and layout paths, resulting in the ability for snaps to inject arbitrary AppArmor policy rules via malformed content interface and layout declarations and hence escape strict snap confinement. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1 | Snapd, Ubuntu_linux, Fedora | 7.8 | ||
| 2022-02-18 | CVE-2020-25717 | A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation. | Ubuntu_linux, Debian_linux, Fedora, Codeready_linux_builder, Enterprise_linux, Enterprise_linux_desktop, Enterprise_linux_eus, Enterprise_linux_for_ibm_z_systems, Enterprise_linux_for_ibm_z_systems_eus, Enterprise_linux_for_power_big_endian, Enterprise_linux_for_power_little_endian, Enterprise_linux_for_power_little_endian_eus, Enterprise_linux_for_scientific_computing, Enterprise_linux_resilient_storage, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_tus, Enterprise_linux_server_update_services_for_sap_solutions, Enterprise_linux_tus, Enterprise_linux_workstation, Gluster_storage, Openstack, Virtualization, Virtualization_host, Samba | 8.1 | ||
| 2022-02-18 | CVE-2020-25719 | A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise. | Ubuntu_linux, Debian_linux, Fedora, Enterprise_linux, Enterprise_linux_desktop, Enterprise_linux_eus, Enterprise_linux_for_ibm_z_systems, Enterprise_linux_for_ibm_z_systems_eus, Enterprise_linux_for_power_big_endian, Enterprise_linux_for_power_little_endian, Enterprise_linux_for_power_little_endian_eus, Enterprise_linux_for_scientific_computing, Enterprise_linux_server_aus, Enterprise_linux_server_tus, Enterprise_linux_server_update_services_for_sap_solutions, Enterprise_linux_workstation, Samba | 7.2 | ||
| 2022-02-18 | CVE-2020-25722 | Multiple flaws were found in the way samba AD DC implemented access and conformance checking of stored data. An attacker could use this flaw to cause total domain compromise. | Ubuntu_linux, Debian_linux, Fedora, Samba | 8.8 | ||
| 2022-02-18 | CVE-2021-4093 | A flaw was found in the KVM's AMD code for supporting the Secure Encrypted Virtualization-Encrypted State (SEV-ES). A KVM guest using SEV-ES can trigger out-of-bounds reads and writes in the host kernel via a malicious VMGEXIT for a string I/O instruction (for example, outs or ins) using the exit reason SVM_EXIT_IOIO. This issue results in a crash of the entire system or a potential guest-to-host escape scenario. | Ubuntu_linux, Fedora, Linux_kernel, Enterprise_linux | 8.8 | ||
| 2022-02-21 | CVE-2021-44142 | The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root. | Ubuntu_linux, Debian_linux, Fedora, Codeready_linux_builder, Enterprise_linux, Enterprise_linux_desktop, Enterprise_linux_eus, Enterprise_linux_for_ibm_z_systems, Enterprise_linux_for_ibm_z_systems_eus, Enterprise_linux_for_power_big_endian, Enterprise_linux_for_power_little_endian, Enterprise_linux_for_power_little_endian_eus, Enterprise_linux_for_scientific_computing, Enterprise_linux_resilient_storage, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_tus, Enterprise_linux_server_update_services_for_sap_solutions, Enterprise_linux_workstation, Gluster_storage, Virtualization_host, Samba, Diskstation_manager | 8.8 | ||
| 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 |
