CVE-2023-2609 [MEDIUM] CWE-476 vim: NULL Pointer Dereference in get_register() at register.c
vim: NULL Pointer Dereference in get_register() at register.c
NULL Pointer Dereference in GitHub repository vim/vim prior to 9.0.1531.
Statement: All versions of Vim shipped with Red Hat Enterprise Linux are affected, because of the presence of vulnerable code in our code-base.
Red Hat Product Security has rated this issue as having a Low security impact, because the "victim" has to run an untrusted file IN SCRIPT MODE. Someone who is running untrusted files in script mode is equivalent to someone just taking a random python script and running it.
Since Red Hat Enterprise Linux 6, 7 are Out-of-Support-Scope for Low/Moderate flaws, the issue is not currently planned to be addressed in future updates for RHEL-6,7. Only Important and Critical severity flaws will be addressed at this time.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
