CVE-2022-23220 4 Canonical, Debian, Gentoo and 1 more 4 Ubuntu Linux, Debian Linux, Linux and 1 more 2026-06-17 7.2 HIGH 7.8 HIGH
USBView 2.1 before 2.2 allows some local users (e.g., ones logged in via SSH) to execute arbitrary code as root because certain Polkit settings (e.g., allow_any=yes) for pkexec disable the authentication requirement. Code execution can, for example, use the --gtk-module option. This affects Ubuntu, Debian, and Gentoo.
CVE-2022-20698 3 Canonical, Clamav, Debian 3 Ubuntu Linux, Clamav, Debian Linux 2026-06-17 5.0 MEDIUM 7.5 HIGH
A vulnerability in the OOXML parsing module in Clam AntiVirus (ClamAV) Software version 0.104.1 and LTS version 0.103.4 and prior versions could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to improper checks that may result in an invalid pointer read. An attacker could exploit this vulnerability by sending a crafted OOXML file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process to crash, resulting in a denial of service condition.
CVE-2022-1804 1 Canonical 2 Accountsservice, Ubuntu Linux 2026-06-17 N/A 5.5 MEDIUM
accountsservice no longer drops permissions when writting .pam_environment
CVE-2022-1736 2 Canonical, Gnome 2 Ubuntu Linux, Gnome-remote-desktop 2026-06-17 N/A 9.8 CRITICAL
Ubuntu's configuration of gnome-control-center allowed Remote Desktop Sharing to be enabled by default.
CVE-2022-1242 1 Canonical 2 Apport, Ubuntu Linux 2026-06-17 N/A 7.8 HIGH

CVE-2022-0543 3 Canonical, Debian, Redis 3 Ubuntu Linux, Debian Linux, Redis 2026-06-17 10.0 HIGH 10.0 CRITICAL
It was discovered, that redis, a persistent key-value database, due to a packaging issue, is prone to a (Debian-specific) Lua sandbox escape, which could result in remote code execution.
CVE-2022-0492 6 Canonical, Debian, Fedoraproject and 3 more 33 Ubuntu Linux, Debian Linux, Fedora and 30 more 2026-06-17 6.9 MEDIUM 7.8 HIGH
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.
CVE-2022-0319 4 Apple, Canonical, Debian and 1 more 4 Macos, Ubuntu Linux, Debian Linux and 1 more 2026-06-17 4.3 MEDIUM 5.5 MEDIUM
Out-of-bounds Read in vim/vim prior to 8.2.
CVE-2021-4120 2 Canonical, Fedoraproject 3 Snapd, Ubuntu Linux, Fedora 2026-06-17 4.6 MEDIUM 8.2 HIGH
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
CVE-2021-4115 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2026-06-17 2.1 LOW 5.5 MEDIUM
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
CVE-2021-4093 4 Canonical, Fedoraproject, Linux and 1 more 4 Ubuntu Linux, Fedora, Linux Kernel and 1 more 2026-06-17 7.2 HIGH 8.8 HIGH
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.
CVE-2021-45417 5 Advanced Intrusion Detection Environment Project, Canonical, Debian and 2 more 7 Advanced Intrusion Detection Environment, Ubuntu Linux, Debian Linux and 4 more 2026-06-17 7.2 HIGH 7.8 HIGH
AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS extended attributes or tmpfs ACLs), because of a heap-based buffer overflow.
CVE-2021-45079 4 Canonical, Debian, Fedoraproject and 1 more 5 Ubuntu Linux, Debian Linux, Extra Packages For Enterprise Linux and 2 more 2026-06-17 5.8 MEDIUM 9.1 CRITICAL
In strongSwan before 5.9.5, a malicious responder can send an EAP-Success message too early without actually authenticating the client and (in the case of EAP methods with mutual authentication and EAP-only authentication for IKEv2) even without server authentication.
CVE-2021-44731 3 Canonical, Debian, Fedoraproject 4 Snapd, Ubuntu Linux, Debian Linux and 1 more 2026-06-17 6.9 MEDIUM 7.8 HIGH
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
CVE-2021-44730 3 Canonical, Debian, Fedoraproject 4 Snapd, Ubuntu Linux, Debian Linux and 1 more 2026-06-17 6.9 MEDIUM 7.8 HIGH
snapd 2.54.2 did not properly validate the location of the snap-confine binary. A local attacker who can hardlink this binary to another location to cause snap-confine to execute other arbitrary binaries 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
CVE-2021-44420 5 Canonical, Debian, Djangoproject and 2 more 5 Ubuntu Linux, Debian Linux, Django and 2 more 2026-06-17 7.5 HIGH 7.3 HIGH
In Django 2.2 before 2.2.25, 3.1 before 3.1.14, and 3.2 before 3.2.10, HTTP requests for URLs with trailing newlines could bypass upstream access control based on URL paths.
CVE-2021-44142 6 Canonical, Debian, Fedoraproject and 3 more 23 Ubuntu Linux, Debian Linux, Fedora and 20 more 2026-06-17 9.0 HIGH 8.8 HIGH
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.
CVE-2021-3975 5 Canonical, Debian, Fedoraproject and 2 more 14 Ubuntu Linux, Debian Linux, Fedora and 11 more 2026-06-17 N/A 6.5 MEDIUM
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.
CVE-2021-3939 1 Canonical 2 Accountsservice, Ubuntu Linux 2026-06-17 7.2 HIGH 7.8 HIGH
Ubuntu-specific modifications to accountsservice (in patch file debian/patches/0010-set-language.patch) caused the fallback_locale variable, pointing to static storage, to be freed, in the user_change_language_authorized_cb function. This is reachable via the SetLanguage dbus function. This is fixed in versions 0.6.55-0ubuntu12~20.04.5, 0.6.55-0ubuntu13.3, 0.6.55-0ubuntu14.1.
