When mounting a share, a malicious AFP server can cause the DSI read path to process a length that exceeds the size requested by the client. The function does not verify the server-provided length against the pre-sized reply buffer, causing the operation to access past the intended boundaries. This issue allows a malicious server to overflow a heap buffer and crash the gvfsd-afp process, resulting in a denial of service.","epss":{"date":"2026-11-05","percentile":0.23107,"score":0.00302},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://gitlab.gnome.org/GNOME/gvfs/-/issues/863"}],"kev":null,"metrics":[{"score":6.5,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1793927153431,"publishedAt":1788275948794,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-84269"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2526784"},{"source":"CNA: redhat","tags":[],"url":"https://gitlab.gnome.org/GNOME/gvfs/-/issues/863"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://gitlab.gnome.org/GNOME/gvfs/-/issues/863"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"To mitigate this vulnerability, do not connect to untrusted AFP servers."}],"revision":"e84cf88d56e2785db7e93c8d153dc6f2c92f3aaab1889cf43ffa42cf54cbd58e","sources":[{"modifiedAt":1793927153431,"name":"CNA: redhat","retrievedAt":1793930966323,"url":"https://www.cve.org/CVERecord?id=CVE-2026-84269"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793931031989,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-84269"}],"ssvc":{"assessedAt":1788487465301,"automatable":"no","exploitation":"poc","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Gvfs: afp: heap-based buffer overflow in dsi read path","updatedAt":1793931031989}
