A vulnerability was identified in vim 9.1.0000. Affected is the function __memmove_avx_unaligned_erms of the file memmove-vec-unaligned-erms.S. The manipulation leads to memory corruption. The attack needs to be performed locally. The exploit is publicly available and might be used. Some users are not able to reproduce this. One of the users mentions that this appears not to be working, "when coloring is turned on".

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1584 advisory.

    When switching to other buffers using the :all command and visual mode still being active, this may cause     a heap-buffer overflow, because Vim does not properly end visual mode and therefore may try to access     beyond the end of a line in a buffer. In Patch 9.1.1003 Vim will correctly reset the visual mode before     opening other windows and buffers and therefore fix this bug. In addition it does verify that it won't try     to access a position if the position is greater than the corresponding buffer line. Impact is medium since     the user must have switched on visual mode when executing the :all ex command. The Vim project would like     to thank github user gandalf4a for reporting this issue. The issue has been fixed as of Vim patch     v9.1.1003 (CVE-2025-22134)

    A vulnerability was identified in vim 9.1.0000. Affected is the function __memmove_avx_unaligned_erms of     the file memmove-vec-unaligned-erms.S. The manipulation leads to memory corruption. The attack needs to be     performed locally. The exploit is publicly available and might be used. Some users are not able to     reproduce this. One of the users mentions that this appears not to be working, when coloring is turned     on. (CVE-2025-9389)

    A security flaw has been discovered in vim up to 9.1.1615. Affected by this vulnerability is the function     main of the file src/xxd/xxd.c of the component xxd. The manipulation results in buffer overflow. The     attack requires a local approach. The exploit has been released to the public and may be exploited.
    Upgrading to version 9.1.1616 addresses this issue. The patch is identified as     eeef7c77436a78cd27047b0f5fa6925d56de3cb0. It is recommended to upgrade the affected component.
    (CVE-2025-9390)

    Vim is an open source, command line text editor. Prior to version 9.1.2132, a heap buffer overflow     vulnerability exists in Vim's tag file resolution logic when processing the 'helpfile' option. The     vulnerability is located in the get_tagfname() function in src/tag.c. When processing help file tags, Vim     copies the user-controlled 'helpfile' option value into a fixed-size heap buffer of MAXPATHL + 1 bytes     (typically 4097 bytes) using an unsafe STRCPY() operation without any bounds checking. This issue has been     patched in version 9.1.2132. (CVE-2026-25749)

    Vim is an open source, command line text editor. Prior to 9.1.2148, a stack buffer overflow vulnerability     exists in Vim's NetBeans integration when processing the specialKeys command, affecting Vim builds that     enable and use the NetBeans feature. The Stack buffer overflow exists in special_keys() (in     src/netbeans.c). The while (*tok) loop writes two bytes per iteration into a 64-byte stack buffer (keybuf)     with no bounds check. A malicious NetBeans server can overflow keybuf with a single specialKeys command.
    The issue has been fixed as of Vim patch v9.1.2148. (CVE-2026-26269)

    Vim is an open source, command line text editor. Prior to version 9.2.0073, an OS command injection     vulnerability exists in the `netrw` standard plugin bundled with Vim. By inducing a user to open a crafted     URL (e.g., using the `scp://` protocol handler), an attacker can execute arbitrary shell commands with the     privileges of the Vim process. Version 9.2.0073 fixes the issue. (CVE-2026-28417)

    Vim is an open source, command line text editor. Prior to version 9.2.0074, a heap-based buffer overflow     out-of-bounds read exists in Vim's Emacs-style tags file parsing logic. When processing a malformed tags     file, Vim can be tricked into reading up to 7 bytes beyond the allocated memory boundary. Version 9.2.0074     fixes the issue. (CVE-2026-28418)

    Vim is an open source, command line text editor. Prior to version 9.2.0075, a heap-based buffer underflow     exists in Vim's Emacs-style tags file parsing logic. When processing a malformed tags file where a     delimiter appears at the start of a line, Vim attempts to read memory immediately preceding the allocated     buffer. Version 9.2.0075 fixes the issue. (CVE-2026-28419)

    Vim is an open source, command line text editor. Prior to version 9.2.0076, a heap-based buffer overflow     WRITE and an out-of-bounds READ exist in Vim's terminal emulator when processing maximum combining     characters from Unicode supplementary planes. Version 9.2.0076 fixes the issue. (CVE-2026-28420)

    Vim is an open source, command line text editor. From 9.1.0011 to before 9.2.0137, Vim's NFA regex     compiler, when encountering a collection containing a combining character as the endpoint of a character     range (e.g. [0-0\u05bb]), incorrectly emits the composing bytes of that character as separate NFA states.
    This corrupts the NFA postfix stack, resulting in NFA_START_COLL having a NULL out1 pointer. When     nfa_max_width() subsequently traverses the compiled NFA to estimate match width for the look-behind     assertion, it dereferences state->out1->out without a NULL check, causing a segmentation fault. This     vulnerability is fixed in 9.2.0137. (CVE-2026-32249)

    A modeline sandbox bypass in Vim allows arbitrary OS command execution when a user opens a crafted file.
    The complete, guitabtooltip and printheader options are missing the P_MLE flag, allowing a modeline to be     executed. Additionally, the mapset() function lacks a check_secure() call, allowing it to be abused from     sandboxed expressions.

    An attacker who can deliver a crafted file to a victim achieves arbitrary command execution with the     privileges of the user running Vim. (CVE-2026-34982)
