CVE-2026-84270 Gvfs: mtp: out-of-bounds read in do_read()

A flaw was found in the MTP backend in gvfs. When reading a file from a mounted MTP device, doread in gvfsbackendmtp.c trusts the data length returned by the device without limiting it to the original size requested by the client. If a malicious MTP device responds with more bytes than requested,...
