AV:N/AC:L/Au:N/C:N/I:N/A:P

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.
