{\"engine\": \"cvelib 1.8.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"A flaw was found in the admin backend of gvfs. 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.\"}], \"problemTypes\": [{\"descriptions\": [{\"lang\": \"en\", \"type\": \"CWE\", \"cweId\": \"CWE-367\", \"description\": \"Time-of-check Time-of-use (TOCTOU) Race Condition\"}]}], \"providerMetadata\": {\"orgId\": \"53f830b8-0a3f-465b-8143-3b8a9948e749\", \"shortName\": \"redhat\", \"dateUpdated\": \"2026-11-04T23:56:25.067Z\"}, \"x_redhatCweChain\": \"CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition\"}}", "cveMetadata": "{\"cveId\": \"CVE-2026-88924\", \"state\": \"PUBLISHED\", \"dateUpdated\": \"2026-11-04T23:56:25.067Z\", \"dateReserved\": \"2026-09-10T14:04:13.603Z\", \"assignerOrgId\": \"53f830b8-0a3f-465b-8143-3b8a9948e749\", \"datePublished\": \"2026-09-10T14:32:30.644Z\", \"assignerShortName\": \"redhat\"}", "dataType": "CVE_RECORD", "dataVersion": "5.2"}}}
