CVE-2023-32233 – kernel: netfilter: use-after-free in nf_tables when processing batch requests can lead to privilege escalation
https://notcve.org/view.php?id=CVE-2023-32233
08 May 2023 — In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled. A use-after-free vulnerability was found in the Netfilter subsystem of the Linux kernel when processing batch requests to update nf_tables configuration. This vulnerability can be abused to perform arbitrary reads and write... • https://github.com/oferchen/POC-CVE-2023-32233 • CWE-416: Use After Free •

CVE-2023-2236 – Use-after-free in Linux kernel's Performance Events subsystem
https://notcve.org/view.php?id=CVE-2023-2236
01 May 2023 — A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local privilege escalation. Both io_install_fixed_file and its callers call fput in a file in case of an error, causing a reference underflow which leads to a use-after-free vulnerability. We recommend upgrading past commit 9d94c04c0db024922e886c9fd429659f22f48ea4. A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local privilege escalation.

CVE-2023-2006 – Linux Kernel RxRPC Race Condition Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2023-2006
13 Apr 2023 — A race condition was found in the Linux kernel's RxRPC network protocol, within the processing of RxRPC bundles. This issue results from the lack of proper locking when performing operations on an object. This may allow an attacker to escalate privileges and execute arbitrary code in the context of the kernel. This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target syste... • https://bugzilla.redhat.com/show_bug.cgi?id=2189112 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

CVE-2023-28531 – Gentoo Linux Security Advisory 202307-01
https://notcve.org/view.php?id=CVE-2023-28531
17 Mar 2023 — ssh-add in OpenSSH before 9.3 adds smartcard keys to ssh-agent without the intended per-hop destination constraints. The earliest affected version is 8.9. Fabian Bäumer, Marcus Brinkmann, Joerg Schwenk discovered that the SSH protocol was vulnerable to a prefix truncation attack. If a remote attacker was able to intercept SSH communications, extension negotiation messages could be truncated, possibly leading to certain algorithms and features being downgraded. This issue is known as the Terrapin attack. • https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AN2UDTXEUSKFIOIYMV6JNI5VSBMYZOFT •
