## What is CVE-2026-1764?

CVE-2026-1764 is a medium-severity memory corruption vulnerability in Redhat Enterprise Linux, published on 16 Jun 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

A flaw was found in GNOME localsearch (previously known as tracker-miners) MP3 Extractor. When processing specially crafted MP3 files containing ID3v2.4 tags, a missing bounds check in the `extract_performers_tags` function can lead to a heap buffer overflow. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by triggering a read of unmapped memory. In some cases, it could also lead to information disclosure by reading visible heap data.

Weakness: CWE-125 (Out-of-bounds Read)

Check this codebase for CVE-2026-1764 and fix it if it is affected.

What it is: CVE-2026-1764 is a medium-severity memory corruption vulnerability in Redhat Enterprise Linux, published on 16 Jun 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2026-1764 in the wild and no public exploit code.

Affected product: Redhat Enterprise Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
