CVE-2023-0386 4 Canonical, Debian, Linux and 1 more 13 Ubuntu Linux, Debian Linux, Linux Kernel and 10 more 2026-06-17 N/A 7.8 HIGH
A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel’s OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount. This uid mapping bug allows a local user to escalate their privileges on the system.
CVE-2023-0179 4 Canonical, Fedoraproject, Linux and 1 more 14 Ubuntu Linux, Fedora, Linux Kernel and 11 more 2026-06-17 N/A 7.8 HIGH
A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution.
CVE-2022-44544 2 Canonical, Mahara 2 Ubuntu Linux, Mahara 2026-06-17 N/A 9.8 CRITICAL
Mahara 21.04 before 21.04.7, 21.10 before 21.10.5, 22.04 before 22.04.3, and 22.10 before 22.10.0 potentially allow a PDF export to trigger a remote shell if the site is running on Ubuntu and the flag -dSAFER is not set with Ghostscript.
CVE-2022-40617 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2026-06-17 N/A 7.5 HIGH
strongSwan before 5.9.8 allows remote attackers to cause a denial of service in the revocation plugin by sending a crafted end-entity (and intermediate CA) certificate that contains a CRL/OCSP URL that points to a server (under the attacker's control) that doesn't properly respond but (for example) just does nothing after the initial TCP handshake, or sends an excessive amount of application data.
CVE-2022-40277 3 Canonical, Joplinapp, Linux 3 Ubuntu Linux, Joplin, Linux Kernel 2026-06-17 N/A 7.8 HIGH
Joplin version 2.8.8 allows an external attacker to execute arbitrary commands remotely on any client that opens a link in a malicious markdown file, via Joplin. This is possible because the application does not properly validate the schema/protocol of existing links in the markdown file before passing them to the 'shell.openExternal' function.
CVE-2022-3328 1 Canonical 2 Snapd, Ubuntu Linux 2026-06-17 N/A 7.8 HIGH
Race condition in snap-confine's must_mkdir_and_open_with_perms()
CVE-2022-39177 3 Bluez, Canonical, Debian 3 Bluez, Ubuntu Linux, Debian Linux 2026-06-17 N/A 8.8 HIGH
BlueZ before 5.59 allows physically proximate attackers to cause a denial of service because malformed and invalid capabilities can be processed in profiles/audio/avdtp.c.
CVE-2022-39176 3 Bluez, Canonical, Debian 3 Bluez, Ubuntu Linux, Debian Linux 2026-06-17 N/A 8.8 HIGH
BlueZ before 5.59 allows physically proximate attackers to obtain sensitive information because profiles/audio/avrcp.c does not validate params_len.
CVE-2022-2585 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2026-06-17 N/A 5.3 MEDIUM
It was discovered that when exec'ing from a non-leader thread, armed POSIX CPU timers would be left on a list but freed, leading to a use-after-free.
CVE-2022-2084 1 Canonical 2 Cloud-init, Ubuntu Linux 2026-06-17 N/A 5.5 MEDIUM
Sensitive data could be exposed in world readable logs of cloud-init before version 22.3 when schema failures are reported. This leak could include hashed passwords.
CVE-2022-29581 4 Canonical, Debian, Linux and 1 more 19 Ubuntu Linux, Debian Linux, Linux Kernel and 16 more 2026-06-17 7.2 HIGH 7.8 HIGH
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.
CVE-2022-28658 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2026-06-17 N/A 5.5 MEDIUM
Apport argument parsing mishandles filename splitting on older kernels resulting in argument spoofing
CVE-2022-28657 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2026-06-17 N/A 7.8 HIGH
Apport does not disable python crash handler before entering chroot
CVE-2022-28656 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2026-06-17 N/A 5.5 MEDIUM
is_closing_session() allows users to consume RAM in the Apport process
CVE-2022-28655 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2026-06-17 N/A 7.1 HIGH
is_closing_session() allows users to create arbitrary tcp dbus connections
CVE-2022-28654 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2026-06-17 N/A 5.5 MEDIUM
is_closing_session() allows users to fill up apport.log
CVE-2022-28652 2 Apport Project, Canonical 2 Apport, Ubuntu Linux 2026-06-17 N/A 5.5 MEDIUM
~/.config/apport/settings parsing is vulnerable to "billion laughs" attack
CVE-2022-24760 3 Canonical, Microsoft, Parseplatform 3 Ubuntu Linux, Windows, Parse-server 2026-06-17 7.5 HIGH 10.0 CRITICAL
Parse Server is an open source http web server backend. In versions prior to 4.10.7 there is a Remote Code Execution (RCE) vulnerability in Parse Server. This vulnerability affects Parse Server in the default configuration with MongoDB. The main weakness that leads to RCE is the Prototype Pollution vulnerable code in the file `DatabaseController.js`, so it is likely to affect Postgres and any other database backend as well. This vulnerability has been confirmed on Linux (Ubuntu) and Windows. Users are advised to upgrade as soon as possible. The only known workaround is to manually patch your installation with code referenced at the source GHSA-p6h4-93qp-jhcm.
CVE-2022-23238 5 Canonical, Centos, Linux and 2 more 5 Ubuntu Linux, Centos, Linux Kernel and 2 more 2026-06-17 N/A 6.5 MEDIUM
Linux deployments of StorageGRID (formerly StorageGRID Webscale) versions 11.6.0 through 11.6.0.2 deployed with a Linux kernel version less than 4.7.0 are susceptible to a vulnerability which could allow a remote unauthenticated attacker to view limited metrics information and modify alert email recipients and content.
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.
