## What is CVE-2026-93433?

CVE-2026-93433 is a medium-severity memory corruption vulnerability in Red Hat Enterprise Linux 10, published on 21 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

A flaw was found in libstoragemgmt. An attacker with control over a local or virtual storage device could provide specially crafted SCSI (Small Computer System Interface) Vital Product Data (VPD) page 0x80 data. This malformed data, specifically an untrusted page length field, can lead to a stack buffer overflow in the `_sg_parse_vpd_80()` function during serial number parsing. Successful exploitation could result in a denial of service by crashing or destabilizing the process querying the serial number.

Weakness: CWE-121 (Stack-based Buffer Overflow)

Check this codebase for CVE-2026-93433 and fix it if it is affected.

What it is: CVE-2026-93433 is a medium-severity memory corruption vulnerability in Red Hat Enterprise Linux 10, published on 21 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-93433 in the wild and no public exploit code.

Affected product: Red Hat Enterprise Linux 10. 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.
