The privileged gvfsd-admin daemon changes the ownership of newly created private D-Bus sockets by calling the link-following chown() function on a pathname inside a user-controlled directory. A local attacker can exploit this via a Time-of-Check Time-of-Use (TOCTOU) race condition and exchange the socket pathname with a symbolic link pointing to an arbitrary root-owned file (such as /etc/pam.d/su). The daemon subsequently follows the symlink and changes the ownership of the targeted root-owned file to the attacker's user ID. This allows an authenticated local attacker to modify critical system files, leading to a full local privilege escalation to root.","epss":{"date":"2026-11-04","percentile":0.1298,"score":0.00223},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://gitlab.gnome.org/GNOME/gvfs/-/issues/875"}],"kev":null,"metrics":[{"score":7,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793836585067,"publishedAt":1789050750644,"references":[{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:73998"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:74370"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:85939"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:85941"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:85942"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:85944"},{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-88924"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2531456"},{"source":"CNA: redhat","tags":[],"url":"https://gitlab.gnome.org/GNOME/gvfs/-/issues/875"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://gitlab.gnome.org/GNOME/gvfs/-/issues/875"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"To mitigate this issue, adjust Polkit rules to require password authentication to start gvfsd-admin or remove execute permissions of the gvfsd-admin binary to prevent execution."}],"revision":"5e07d0cb6ab568646340aa498db91de58f62080126ac00eee9ef615f8cd517c0","sources":[{"modifiedAt":1793836585067,"name":"CNA: redhat","retrievedAt":1793837388719,"url":"https://www.cve.org/CVERecord?id=CVE-2026-88924"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793837391915,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-88924"}],"ssvc":{"assessedAt":1789061554743,"automatable":"no","exploitation":"poc","source":"ADP: CISA-ADP","technicalImpact":"total"},"status":"published","title":"Gvfs: gvfs-admin socket ownership race permits local root","updatedAt":1793837391915}
