https://notcve.org/view.php?id=CVE-2023-2612
30 May 2023 — 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). It was discovered that the OverlayFS implementation in the Linux kernel did not properly handle copy up operation in some conditions. A local attacker could possibly use this to gain elevated privileges. It was discovered that the Broadcom FullMAC USB WiFi driver in th... • http://packetstormsecurity.com/files/173087/Kernel-Live-Patch-Security-Notice-LSN-0095-1.html • CWE-667: Improper Locking •

26 Apr 2023 — 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. A vulnerability was found in cloud-init. With this flaw, exposure of sensitive data is possible in world-readable cloud-init logs. This flaw allows an attacker to use this information to find hashed passwords and possibly escalate their privilege. • https://bugs.launchpad.net/cloud-init/+bug/2013967 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-532: Insertion of Sensitive Information into Log File •

13 Apr 2023 — 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.

24 Jan 2023 — A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution. Davide Ornaghi discovered that the netfilter subsystem in the Linux kernel did not properly handle VLAN headers in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
