| CVE-2021-4034 | 7 Canonical, Oracle, Polkit Project and 4 more | 31 Ubuntu Linux, Http Server, Zfs Storage Appliance Kit and 28 more | 2026-08-15 | 7.2 HIGH | 7.8 HIGH |
| A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine. | |||||

| CVE-2026-31431 | 10 Amazon, Arista, Canonical and 7 more | 47 Amazon Linux, Cloudvision Agni, Cloudvision Portal and 44 more | 2026-07-28 | N/A | 7.8 HIGH |
| In the Linux kernel, the following vulnerability has been resolved: crypto: algif_aead - Revert to operating out-of-place This mostly reverts commit 72548b093ee3 except for the copying of the associated data. There is no benefit in operating in-place in algif_aead since the source and destination come from different mappings. Get rid of all the complexity added for in-place operation and just copy the AD directly. | |||||
| CVE-2025-68153 | 1 Canonical | 1 Juju | 2026-07-24 | N/A | 6.5 MEDIUM |
| Juju is an open source application orchestration engine that enables any application operation on any infrastructure at any scale through special operators called ‘charms’. From versions 2.9 to before 2.9.56 and 3.6 to before 3.6.19, any authenticated user, machine or controller under a Juju controller can modify the resources of an application within the entire controller. This issue has been patched in versions 2.9.56 and 3.6.19. | |||||
| CVE-2025-68152 | 1 Canonical | 1 Juju | 2026-07-24 | N/A | 4.9 MEDIUM |
| Juju is an open source application orchestration engine that enables any application operation on any infrastructure at any scale through special operators called ‘charms’. From versions 2.9 to before 2.9.56 and 3.6 to before 3.6.19, it is possible that a compromised workload machine under a Juju controller can read any log file for any entity in any model at any level.

| CVE-2026-3497 | 4 Canonical, Debian, Openbsd and 1 more | 4 Ubuntu Linux, Debian Linux, Openssh and 1 more | 2026-07-15 | N/A | 7.5 HIGH |
| Vulnerability in the OpenSSH GSSAPI delta included in various Linux distributions. This vulnerability affects the GSSAPI patches added by various Linux distributions and does not affect the OpenSSH upstream project itself. The usage of sshpkt_disconnect() on an error, which does not terminate the process, allows an attacker to send an unexpected GSSAPI message type during the GSSAPI key exchange to the server, which will call the underlying function and continue the execution of the program without setting the related connection variables. As the variables are not initialized to NULL the code later accesses those uninitialized variables, accessing random memory, which could lead to undefined behavior. The recommended workaround is to use ssh_packet_disconnect() instead, which does terminate the process. The impact of the vulnerability depends heavily on the compiler flag hardening configuration. | |||||

| It was found that the raw midi kernel driver does not protect against concurrent access which leads to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part of snd_rawmidi_ioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for privilege escalation. | |||||
| CVE-2026-28385 | 1 Canonical | 1 Lxd | 2026-07-06 | N/A | 5.0 MEDIUM |
| In Canonical LXD versions 4.12 through 6.9, a Server-Side Request Forgery (SSRF) vulnerability in the image import functionality allows authenticated users with the can_create_images entitlement to interact with internal network infrastructure via the /images endpoint. When importing an image from a URL source, the LXD daemon fails to validate or restrict outbound destination IP addresses, allowing connections to loopback, RFC1918 private ranges, and cloud metadata endpoints. This enables error-based port scanning and unauthorized interaction with internal HTTP services from the daemon's network position. | |||||
| CVE-2026-12411 | 1 Canonical | 1 Lxd | 2026-07-02 | N/A | 8.4 HIGH |
| Broken Access Control in the devLXDInstancePatchHandler component of Canonical LXD allows an untrusted guest to mount, read, and overwrite another guest's custom storage volume via a crafted device PATCH request over /dev/lxd when security.devlxd.management.volumes is enabled. | |||||
| CVE-2026-9639 | 2 Canonical, Linux | 2 Lxd, Linux Kernel | 2026-07-02 | N/A | 6.5 MEDIUM |
| Nil-pointer dereference in CreateCustomVolumeFromBackup in LXD up to version 6.8 and 5.21 on Linux allows an authenticated user with can_create_storage_volumes permissions to cause a denial of service via a specially crafted custom-volume backup tarball that omits the expires_at snapshot field. | |||||
| CVE-2026-9640 | 1 Canonical | 1 Lxd | 2026-07-02 | N/A | 7.2 HIGH |
| A privilege escalation vulnerability exists in LXD from 6.0 before 6.9, 5.21.0 before 5.21.5, and 5.0.0 before 5.0.7 regarding the handling of project-restriction policies during snapshot restoration.. An authenticated project operator in a restricted multi-tenant environment can bypass policy restrictions by importing a maliciously crafted instance backup containing restricted configuration keys within a snapshot. When the snapshot is restored, these restricted keys are applied to the live instance without policy validation. Starting the modified instance grants the operator unauthorized host root access. | |||||
| CVE-2025-26466 | 3 Canonical, Debian, Openbsd | 3 Ubuntu Linux, Debian Linux, Openssh | 2026-06-30 | N/A | 5.9 MEDIUM |
| A flaw was found in the OpenSSH package. For each ping packet the SSH server receives, a pong packet is allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled increase in memory consumption on the server side. Consequently, the server may become unavailable, resulting in a denial of service attack. | |||||
| CVE-2026-6369 | 1 Canonical | 1 Livepatch Client | 2026-06-17 | N/A | 5.5 MEDIUM |
| An improper access control vulnerability in the canonical-livepatch snap client prior to version 10.15.0 allows a local unprivileged user to obtain a sensitive, root-level authentication token by sending an unauthenticated request to the livepatchd.sock Unix domain socket. This vulnerability is exploitable on systems where an administrator has already enabled the Livepatch client with a valid Ubuntu Pro subscription. This token allows an attacker to access Livepatch services using the victim's credentials, as well as potentially cause issues to the Livepatch server. | |||||
| CVE-2026-5774 | 1 Canonical | 1 Juju | 2026-06-17 | N/A | 6.4 MEDIUM |
| Improper synchronization of the userTokens map in the API server in Canonical Juju 4.0.5, 3.6.20, and 2.9.56 may allow an authenticated user to possibly cause a denial of service on the server or possibly reuse a single-use discharge token. | |||||
