| CVE | Severity | CVSS | Published | Summary |
|---|---|---|---|---|
| CVE-2024-6387 | HIGH | 8.1 | Jul 1, 2024 | A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period. |
| CVE-2026-31431 | HIGH | 7.8 | Apr 22, 2026 | 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-2023-45866 | MEDIUM | 6.3 | Dec 8, 2023 | 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-2023-5536 | MEDIUM | 5.0 | Dec 12, 2023 | 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-2023-5616 | MEDIUM | 4.9 | Apr 15, 2025 | 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. |
