CVE-2023-5616 2 Canonical, Gnome 2 Ubuntu Linux, Control Center 2026-06-17 N/A 4.9 MEDIUM
In Ubuntu, gnome-control-center did not properly reflect SSH remote login status when the system was configured to use systemd socket activation for openssh-server. This could unknowingly leave the local machine exposed to remote SSH access contrary to expectation of the user.
CVE-2023-5536 1 Canonical 1 Ubuntu Linux 2026-06-17 N/A 5.0 MEDIUM
A feature in LXD (LP#1829071), affects the default configuration of Ubuntu Server which allows privileged users in the lxd group to escalate their privilege to root without requiring a sudo password.
CVE-2023-45866 6 Apple, Bluproducts, Canonical and 3 more 16 Ipados, Iphone Os, Iphone Se and 13 more 2026-06-17 N/A 6.3 MEDIUM
Bluetooth HID Hosts in BlueZ may permit an unauthenticated Peripheral role HID Device to initiate and establish an encrypted connection, and accept HID keyboard reports, potentially permitting injection of HID messages when no user interaction has occurred in the Central role to authorize such access. An example affected package is bluez 5.64-0ubuntu1 in Ubuntu 22.04LTS. NOTE: in some cases, a CVE-2020-0556 mitigation would have already addressed this Bluetooth HID Hosts issue.
CVE-2023-44216 7 Amd, Apple, Canonical and 4 more 16 Ryzen 5 7600x, Ryzen 7 4800u, M1 Mac Mini and 13 more 2026-06-17 N/A 5.3 MEDIUM
PVRIC (PowerVR Image Compression) on Imagination 2018 and later GPU devices offers software-transparent compression that enables cross-origin pixel-stealing attacks against feTurbulence and feBlend in the SVG Filter specification, aka a GPU.zip issue. For example, attackers can sometimes accurately determine text contained on a web page from one origin if they control a resource from a different origin.
CVE-2023-3567 3 Canonical, Linux, Redhat 3 Ubuntu Linux, Linux Kernel, Enterprise Linux 2026-06-17 N/A 7.1 HIGH
A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux Kernel. This issue may allow an attacker with local user access to cause a system crash or leak internal kernel information.
CVE-2023-3297 2 Canonical, Linux 3 Accountsservice, Ubuntu Linux, Linux Kernel 2026-06-17 N/A 8.1 HIGH
In Ubuntu's accountsservice an unprivileged local attacker can trigger a use-after-free vulnerability in accountsservice by sending a D-Bus message to the accounts-daemon process.
CVE-2023-35788 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
An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7. It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets. This may result in denial of service or privilege escalation.
CVE-2023-32629 1 Canonical 1 Ubuntu Linux 2026-06-17 N/A 7.8 HIGH
Local privilege escalation vulnerability in Ubuntu Kernels overlayfs ovl_copy_up_meta_inode_data skip permission checks when calling ovl_do_setxattr on Ubuntu kernels
CVE-2023-31248 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2026-06-17 N/A 7.8 HIGH
Linux Kernel nftables Use-After-Free Local Privilege Escalation Vulnerability; `nft_chain_lookup_byid()` failed to check whether a chain was active and CAP_NET_ADMIN is in any user or network namespace
CVE-2023-31026 6 Canonical, Citrix, Linux-kvm and 3 more 6 Ubuntu Linux, Hypervisor, Kernel Virtual Machine and 3 more 2026-06-17 N/A 6.0 MEDIUM
NVIDIA vGPU software for Windows and Linux contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where a NULL-pointer dereference may lead to denial of service.
CVE-2023-31022 8 Canonical, Citrix, Linux and 5 more 9 Ubuntu Linux, Hypervisor, Linux Kernel and 6 more 2026-06-17 N/A 5.5 MEDIUM
NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode layer, where a NULL-pointer dereference may lead to denial of service.
CVE-2023-31021 7 Canonical, Citrix, Linux-kvm and 4 more 7 Ubuntu Linux, Hypervisor, Kernel Virtual Machine and 4 more 2026-06-17 N/A 5.5 MEDIUM
NVIDIA vGPU software for Windows and Linux contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where a malicious user in the guest VM can cause a NULL-pointer dereference, which may lead to denial of service.
CVE-2023-31018 8 Canonical, Citrix, Linux and 5 more 9 Ubuntu Linux, Hypervisor, Linux Kernel and 6 more 2026-06-17 N/A 6.5 MEDIUM
NVIDIA GPU Driver for Windows and Linux contains a vulnerability in the kernel mode layer, where an unprivileged regular user can cause a NULL-pointer dereference, which may lead to denial of service.
CVE-2023-2640 1 Canonical 1 Ubuntu Linux 2026-06-17 N/A 7.8 HIGH
On Ubuntu kernels carrying both c914c0e27eb0 and "UBUNTU: SAUCE: overlayfs: Skip permission checking for trusted.overlayfs.* xattrs", an unprivileged user may set privileged extended attributes on the mounted files, leading them to be set on the upper files without the appropriate security checks.
CVE-2023-2612 1 Canonical 1 Ubuntu Linux 2026-06-17 N/A 4.4 MEDIUM
Jean-Baptiste Cayrou discovered that the shiftfs file system in the Ubuntu Linux kernel contained a race condition when handling inode locking in some situations. A local attacker could use this to cause a denial of service (kernel deadlock).
CVE-2023-24492 2 Canonical, Citrix 2 Ubuntu Linux, Secure Access Client 2026-06-17 N/A 9.6 CRITICAL
A vulnerability has been discovered in the Citrix Secure Access client for Ubuntu which, if exploited, could allow an attacker to remotely execute code if a victim user opens an attacker-crafted link and accepts further prompts.
CVE-2023-1786 2 Canonical, Fedoraproject 3 Cloud-init, Ubuntu Linux, Fedora 2026-06-17 N/A 5.5 MEDIUM
Sensitive data could be exposed in logs of cloud-init before version 23.1.2. An attacker could use this information to find hashed passwords and possibly escalate their privilege.
CVE-2023-1523 1 Canonical 2 Snapd, Ubuntu Linux 2026-06-17 N/A 10.0 CRITICAL
Using the TIOCLINUX ioctl request, a malicious snap could inject contents into the input of the controlling terminal which could allow it to cause arbitrary commands to be executed outside of the snap sandbox after the snap exits. Graphical terminal emulators like xterm, gnome-terminal and others are not affected - this can only be exploited when snaps are run on a virtual console.
CVE-2023-1326 1 Canonical 2 Apport, Ubuntu Linux 2026-06-17 N/A 7.7 HIGH
A privilege escalation attack was found in apport-cli 2.26.0 and earlier which is similar to CVE-2023-26604. If a system is specially configured to allow unprivileged users to run sudo apport-cli, less is configured as the pager, and the terminal size can be set: a local attacker can escalate privilege. It is extremely unlikely that a system administrator would configure sudo to allow unprivileged users to perform this class of exploit.
CVE-2023-1032 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2026-06-17 N/A 4.7 MEDIUM
The Linux kernel io_uring IORING_OP_SOCKET operation contained a double free in function __sys_socket_file() in file net/socket.c. This issue was introduced in da214a475f8bd1d3e9e7a19ddfeb4d1617551bab and fixed in 649c15c7691e9b13cbe9bf6c65c365350e056067.
