What is CVE-2023-3269?
CVE-2023-3269 is a high-severity vulnerability affecting the memory management subsystem of the Linux kernel. This issue can be exploited to execute arbitrary kernel code, escalate containers, and gain root privileges on Linux-based systems running affected versions of the kernel. The vulnerability arises from incorrect lock handling for accessing and updating virtual memory areas (VMAs), leading to use-after-free problems. It is crucial for users of Linux-based systems to be aware of this vulnerability and take appropriate measures to secure their systems.
Who is impacted?
The CVE-2023-3269 vulnerability affects users of the Linux kernel's memory management subsystem. Specifically, it impacts Linux kernel versions from 6.1 up to 6.1.37, 6.2 up to 6.3.11, and 6.4 (including release candidates). Additionally, Fedora Project Fedora versions 37 and 38, as well as Red Hat Enterprise Linux versions 6.0, 7.0, 8.0, and 9.0, are affected. This issue can lead to privilege escalation and unauthorized access, making it crucial for users to be aware of the vulnerability and take appropriate measures to secure their systems.
