Doc Text:
A NULL pointer dereference flaw was found in vim's vim_regexec_string() function in regexp.c file. The issue occurs when the function tries to match the buffer with an invalid pattern. This flaw allows an attacker to trick a user into opening a specially crafted file, triggering a NULL pointer dereference that causes an application to crash, leading to a denial of service.
