TIMELINE

Sep 1 Published (CNA: redhat)
Sep 30 PATCH SHIPPED — CVE-2026-84268 (GNOME gvfs). Fixed in Red Hat Enterprise Linux 10 0:1.54.4-4.el10_2.1.
Description
A flaw was found in the SFTP backend in gvfs. When mounting a share and reading a file, a malicious SFTP server can cause read_reply() to process a length that exceeds the size requested by the client. The function does not verify the server-provided length against the allocated buffer size, causing the operation to write past the intended boundaries. This issue allows a malicious server to corrupt adjacent heap memory in the gvfsd-sftp process, resulting in a denial of service as the process aborts upon detecting the heap corruption or potentially allowing arbitrary code execution.
