CVE-2026-73070
PUBLISHED
CVSS 6.8 MEDIUM
Reported by GitHub_M · Published August 11, 2026
Vim is an open source, command line text editor. Prior to 9.2.0842, the socket server backend in src/socketserver.c accepts unbounded client connections in socketserver_accept(), causing descriptors to overflow fd_set structures in src/channel.c and fixed-size struct pollfd arrays in src/os_unix.c, which allows a local process that can connect to the server socket to corrupt stack memory or terminate the Vim server. This issue is fixed in version 9.2.0842.
