Summary
gvfs vulnerabilities
Details

Keith Linneman discovered that GVfs did not properly validate data received from SFTP servers. An attacker could possibly use this issue to cause a heap buffer overflow, resulting in arbitrary code execution or a denial of service. (CVE-2026-84268)

It was discovered that GVfs incorrectly handled file ownership when creating private D-Bus sockets in the admin backend. A local attacker could possibly use this issue to change the ownership of arbitrary system files, resulting in privilege escalation to root. This issue only affected Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 26.04 LTS. (CVE-2026-88924)
