4809998625c6770bf24721a33e8e7f18This Metasploit module attempts to gain root privileges on Linux systems by abusing a NULL pointer dereference in the rds_atomic_free_op function in the Reliable Datagram Sockets (RDS) kernel module (rds.ko). Successful exploitation requires the RDS kernel module to be loaded. If the RDS module is not blacklisted (default); then it will be loaded automatically. This exploit supports 64-bit Ubuntu Linux systems, including distributions based on Ubuntu, such as Linux Mint and Zorin OS. This exploit does not bypass SMAP. Bypasses for SMEP and KASLR are included. Failed exploitation may crash the kernel. This module has been tested successfully on various 4.4 and 4.8 kernels.

dbc5f5b20329ede3b61e960c453e1e6aXNU has an issue where missing locking in checkdirs_callback() enables a race condition with fchdir_common().
85e06607829ab208006bfe5a5ef59847This Metasploit module exploits an issue in ptrace_link in kernel/ptrace.c before Linux kernel 5.1.17. This issue can be exploited from a Linux desktop terminal, but not over an SSH session, as it requires execution from within the context of a user with an active Polkit agent. In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME.
a67b52657090e25d42aa370f66e7ca88XNU suffers from a remote double-free vulnerability due to a data race in IPComp input path.

934ee0432bced903b9c092168a681f86Linux suffers from a missing locking between ELF coredump code and userfaultfd VMA modification.
6e83b659aeebd1f611e769f9fff5b64bThis bug report describes a bug in systemd that allows a service with DynamicUser in collaboration with another service or user to create a setuid binary that can be used to access its UID beyond the lifetime of the service. This bug probably has relatively low severity, given that there are not many services yet that use DynamicUser, and the requirement of collaboration with another process limits the circumstances in which it would be useful to an attacker further; but in a system that makes heavy use of DynamicUser, it would probably have impact.
cb138590286ec36c3796f89c3e18cff6The Siemens R3964 line discipline code in drivers/tty/n_r3964.c has a few races around its ioctl handler; for example, the handler for R3964_ENABLE_SIGNALS just allocates and deletes elements in a linked list with zero locking. This code is reachable by an unprivileged user if the line discipline is enabled in the kernel config; Ubuntu 18.04, for example, ships this line discipline as a module.
1820caa252c106e5cc11b80e59c7e65cLinux suffers from a page->_refcount overflow via FUSE with ~140GiB RAM usage.
