CVE-2018-10906 | BDVDB-2026-105035 Detail
[UNKNOWN]fuse
Description#
In fuse before versions 2.9.8 and 3.x before 3.2.5, fusermount is vulnerable to a restriction bypass when SELinux is active. This allows non-root users to mount a FUSE file system with the 'allow_other' mount option regardless of whether 'user_allow_other' is set in the fuse configuration. An attacker may use this flaw to mount a FUSE file system, accessible by other users, and trick them into accessing files on that file system, possibly causing Denial of Service or other unspecified effects.
Impact#
Per CVSS v3.0: confidentiality impact low, integrity impact low, availability impact low. Attack vector: local.
