CVE-2026-84270

Name of the Vulnerable Software and Affected Versions gvfs (affected versions not specified)

Description A flaw exists in the MTP backend of gvfs. When reading a file from a mounted MTP device, the do read() function in gvfsbackendmtp.c trusts the data length returned by the device without limiting it to the size requested by the client. If a malicious MTP device provides more bytes than requested, this length is passed to memcpy(), causing an out-of-bounds read. This can lead to a segmentation fault and crash the gvfsd-mtp process, resulting in a denial of service.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
