Vulnerability Details
The vulnerability description indicates an out-of-bounds write in accessing uninitialized memory for svc1td in libsthmbc.so prior to SMR Jan-2025 Release 1. The CVSS base score is 7.8, with a high severity classification. The affected product is Samsung Android, and the vulnerability was disclosed on February 4, 2025. The CWE classification is CWE-787.
Technical Analysis
The root cause of this vulnerability is due to improper handling of memory operations, leading to an out-of-bounds write condition. The attack vector is local, meaning that an attacker must have physical access to the device. The attack complexity is classified as high, requiring specific conditions to be met. Importantly, no privileges are required, and user interaction is necessary to trigger the vulnerability.
In terms of impact, this vulnerability poses high risks to confidentiality, integrity, and availability. An attacker could potentially manipulate sensitive data or disrupt services.
Risk & Impact Analysis
Real-world deployment risk is significant due to the potential for local attackers to exploit this vulnerability if they gain access to devices. Organizations must consider the blast radius, as the impact could extend to sensitive user data and operational disruptions.
Given the CVSS score, organizations should address this vulnerability in their priority patch cycle. The urgency for remediation is high, and failure to act could lead to serious security incidents.
