Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Ongoing control assessments and code testing (static/dynamic analysis, fuzzing) surface memory buffer restriction failures, which are then remediated before release.
Managed runtimes used by platform-independent applications (e.g., JVM, CLR) enforce memory safety, preventing most buffer overflows that require direct memory manipulation.
Memory protections (e.g., W^X, ASLR) make exploitation of buffer-boundary violations far harder to turn into code execution.
Detects exploitation attempts that produce memory corruption, crashes, or anomalous behavior.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Out-of-bounds read in libvips enables local memory disclosure of sensitive data, directly facilitating collection from local system sources.
NVD Description
A vulnerability has been found in libvips 8.19.0. This issue affects the function vips_extract_band_build of the file libvips/conversion/extract.c. The manipulation of the argument extract_band leads to out-of-bounds read. The attack needs to be performed locally. The exploit has been disclosed…

Deeper analysisAI
CVE-2026-3283 is an out-of-bounds read vulnerability in libvips version 8.19.0, affecting the vips_extract_band_build function within the file libvips/conversion/extract.c. The issue arises from manipulation of the extract_band argument, which can trigger improper memory access beyond allocated bounds. This flaw is classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-125 (Out-of-bounds Read), with a CVSS v3.1 base score of 3.3.
Exploitation requires local access (AV:L) with low attack complexity (AC:L) and low privileges (PR:L), needing no user interaction (UI:N) and maintaining unchanged scope (S:U). A local attacker could trigger the vulnerability to achieve low-impact confidentiality loss (C:L), such as reading sensitive data from memory, with no impact on integrity (I:N) or availability (A:N). The exploit has been publicly disclosed and may be usable.
Mitigation is available via a patch identified by commit 24795bb3d19d84f7b6f5ed86451ad556c8f2fe70 in the libvips GitHub repository. Security practitioners should deploy this patch promptly to affected libvips installations. Related discussions and the fix are documented in GitHub issues #4880 and pull request #4887.
