Technical analysis

Mechanism and impact are interpreted from ingested advisories — not independent exploit research.

  • CWE classification

    No CWE identifiers stored yet.

  • Prerequisites and impact

    Follow the original vendor advisory for access prerequisites and impact. This catalog does not invent exploit conditions.

How to fix SUSE-SU-2026:4706-1

  • Recommended remediation

    A patch or advisory reference is linked. Open the original publisher for availability by product version.

  • Official advisories

What to do

Three reads of the same public record: the decision, the versions on file, and the signals. Confirm the vendor advisory before you patch. This page does not publish exploit steps.

Executive

This is a public record, not a confirmed incident. SUSE-SU-2026:4706-1 is a unscored issue in the affected product (Unscored severity). CISA does not currently list it as known exploited. Next step: Compare installed versions with the linked vendor advisory before changing production.

System administrator

Check whether the affected product is installed. Ranges on record: kernel-default (0 → 6.4.0-150700.53.84.1); kernel-livepatch-SLE15-SP7_Update_22 (0 → 1-150700.15.3.1); kernel-64kb (0 → 6.4.0-150700.53.84.1); kernel-default (0 → 6.4.0-150700.53.84.1). Compare installed versions with the linked vendor advisory before changing production.
