| CVE-2023-3389 | 3 Canonical, Debian, Linux | 3 Ubuntu Linux, Debian Linux, Linux Kernel | 2024-11-21 | N/A | 7.8 HIGH |
| A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local privilege escalation. Racing a io_uring cancel poll request with a linked timeout can cause a UAF in a hrtimer. We recommend upgrading past commit ef7dfac51d8ed961b742218f526bd589f3900a59 (4716c73b188566865bdd79c3a6709696a224ac04 for 5.10 stable and 0e388fce7aec40992eadee654193cad345d62663 for 5.15 stable). | |||||
| CVE-2023-3297 | 2 Canonical, Linux | 3 Accountsservice, Ubuntu Linux, Linux Kernel | 2024-11-21 | 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 | 2024-11-21 | 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. | |||||

| 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 | 2024-11-21 | 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 | 2024-11-21 | 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 | 2024-11-21 | 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 | 2024-11-21 | 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 | 2024-11-21 | 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 | 2024-11-21 | 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 | 2024-11-21 | 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. | |||||
