| CVE-2026-31431 KEV | 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. | 416baaa9-dc9f-4396-8d5f-8c081fb06d67 | 7.8 | 96.27% | 2026-04-22 | 2026-07-14 |

| CVE-2026-3497 | 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 with | [email protected] | 6.9 | 2.18% | 2026-03-12 | 2026-07-14 |
| CVE-2025-32463 KEV | Sudo before 1.9.17p1 allows local users to obtain root access because /etc/nsswitch.conf from a user-controlled directory is used with the --chroot option. | [email protected] | 9.3 | 48.24% | 2025-06-30 | 2026-06-17 |
| CVE-2025-5054 | Race condition in Canonical apport up to and including 2.32.0 allows a local attacker to leak sensitive information via PID-reuse by leveraging namespaces. When handling a crash, the function `_check_global_pid_and_forward`, which detects if the crashing process resided in a container, was being called before `consistency_checks`, which attempts to detect if the crashing process had been replaced. Because of this, if a process crashed and was quickly replaced with a containerized one, apport | [email protected] | 4.7 | 0.67% | 2025-05-30 | 2026-06-17 |
| CVE-2023-5616 | 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. | [email protected] | 4.9 | 0.19% | 2025-04-15 | 2026-06-17 |

| CVE-2025-26466 | 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. | [email protected] | 5.9 | 38.47% | 2025-02-28 | 2026-06-29 |
