The TFTP server can serve the wrong file contents because a recently used transfer cache is not invalidated when a transfer finishes. An attacker on the local network who can request a TFTP file may cause a later client to receive previously cached data instead of the requested file. In PXE network-boot environments this can substitute attacker-chosen boot content for a victim machine.","epss":{"date":"2026-11-02","percentile":0.22981,"score":0.00302},"exploits":[],"kev":null,"metrics":[{"score":6.8,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"}],"modifiedAt":1793652899284,"publishedAt":1793278043431,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-93006"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2536075"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"The following measures reduce risk:\n\n1.
