A local, low-privileged attacker can exploit a race condition during privileged instance migration by manipulating a temporary file in the `/tmp` directory. By repeatedly recreating a symbolic link, the attacker can redirect privileged output to an arbitrary file. This can lead to privileged file corruption or a denial of service (DoS) on the system.","epss":{"date":"2026-11-05","percentile":0.02344,"score":0.00126},"exploits":[],"kev":null,"metrics":[{"score":6.3,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:H","version":"3.1"}],"modifiedAt":1793919365702,"publishedAt":1786625056778,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-73584"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2462721"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"To mitigate this issue, if instance migration is not required, run the `sfcbrepos` command with the `-i` option to disable the vulnerable migration path.
