A local attacker with administrative privileges can cause data corruption when saving metadata to a Linux Unified Key Setup (LUKS) device. Due to incorrect boundary calculations and flawed overlap detection, new metadata entries can be written beyond available free space or over existing records. This issue can corrupt stored encrypted payload data or existing metadata, potentially rendering the affected data inaccessible.","epss":{"date":"2026-11-05","percentile":0.00851,"score":0.001},"exploits":[],"kev":null,"metrics":[{"score":5.1,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:L","version":"3.1"},{"score":5.1,"severity":"medium","source":"NVD: secalert@redhat.com","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:L","version":"3.1"}],"modifiedAt":1793895451610,"publishedAt":1791470368679,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-107565"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2547930"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/security/cve/CVE-2026-107565"},{"source":"secalert@redhat.com","tags":[],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2547930"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability."}],"revision":"931242fc89c2becee247eca5db20a2bac024f13b93d568d715179fccc5480015","sources":[{"modifiedAt":1793894124837,"name":"CNA: redhat","retrievedAt":1793895265913,"url":"https://www.cve.org/CVERecord?id=CVE-2026-107565"},{"modifiedAt":1793895451610,"name":"NVD","retrievedAt":1793902862523,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107565"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793895281928,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-107565"}],"ssvc":{"assessedAt":1791480461417,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Luksmeta: incomplete gap-boundary and overlap checks in luks1 metadata allocator allow data corruption","updatedAt":1793902862523}
