CVE-2026-57454: Vim is an open source, command line text editor

Routine

MEDIUM 6.1UPGRADE

CVE-2026-57454 is a medium-severity flaw (CVSS 6.1) affecting vim. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Vim is an open source, command line text editor. From 9.2.0320 until 9.2.0679, a crafted undo or swap file can store a virtual-text property whose offset and length point outside the line's property data. When Vim restores or displays such a line it converts the offset into a pointer and reads the virtual text without bounds checking, causing an out-of-bounds read that can crash Vim or disclose adjacent heap memory. This vulnerability is fixed in

vim vim UPGRADE

Affected: >= 9.2.0320 and < 9.2.0679

Fixed in: 9.2.0679

Safe to downgrade to: a release before 9.2.0320

1. Check installed version

apt-cache policy vim || rpm -q vim || vim --version

2. UPGRADE to 9.2.0679 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade vim

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade vim

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 9.2.0320 (Debian / Ubuntu)

apt-cache madison vim sudo apt install vim=<VERSION_BEFORE_9.2.0320> sudo apt-mark hold vim

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list vim sudo dnf downgrade vim-<VERSION_BEFORE_9.2.0320> sudo dnf versionlock add vim

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
