Vim · Vim · CVE-2023-48231
**Name of the Vulnerable Software and Affected Versions**
Vim versions prior to 9.0.2106
**Description**
The issue is related to the function `win close()` in the text editor Vim, where it may try to access an already freed window structure when closing a window. This could potentially allow an attacker to impact the confidentiality, integrity, and availability of data. However, exploitation beyond crashing the application has not been shown to be viable.
**Recommendations**
For versions prior to 9.0.2106, upgrade to release version 9.0.2106 or later, as this issue has been addressed in commit `25aabc2b` included in this release. As a temporary workaround, consider avoiding the use of the `win close()` function until a patch is available. However, it is noted that there are no known workarounds for this vulnerability.
