Out-of-bounds write in Samsung Notes prior to version 4.4.45.5 allows local attackers to write out-of-bounds memory.
AnalysisAI
Out-of-bounds write in Samsung Notes prior to version 4.4.45.5 allows a local low-privileged attacker to corrupt memory beyond allocated buffer boundaries, resulting in high confidentiality impact and minor integrity and availability effects. The CVSS 4.0 vector (AV:L/PR:L/UI:N/VC:H) confirms local access with low privileges is sufficient, with no user interaction required after the attacker establishes presence. …
