The flaw does not appear in the CISA KEV catalog, suggesting it has not been widely exploited in the wild. However, exploitation requires local privileged access, meaning any user or application that can gain root or system-level privileges on the device could use this vulnerability to execute arbitrary code. Consequently, the risk is moderate for devices that expose privileged user accounts and high for devices that allow installation of privileged applications without stringent checks."}}}}, "created": "2026-01-09T13:23:45.561949+00:00", "title": "Use\u2011after\u2011free in DualDAR allows local privileged code execution", "updated": "2026-04-18T16:45:05.224356+00:00", "vendors": ["samsung", "samsung$PRODUCT$mobile", "samsung$PRODUCT$samsung_mobile"]}
