CVE-2024-31958

Vulnerability

The Samsung Exynos 2200, Exynos 1480, and Exynos 2400 mobile processors are affected by a vulnerability in the handling of native handles. The issue stems from a missing validation check for native handles, which can result in an Out-of-Bounds Write. This affects the graphics or multimedia processing components that utilize native handles for memory management. [1]

Exploitation

An attacker with local access or the ability to execute code on the device may craft a malicious native handle to trigger the out-of-bounds write. Exploitation requires the ability to send requests that pass handles to the vulnerable driver or kernel component. The specific privileges needed are not detailed, but it likely requires user-level or limited kernel access to interact with the relevant interfaces. [1]

Impact

Successful exploitation could lead to memory corruption, potentially allowing the attacker to execute arbitrary code, escalate privileges, or crash the system. The out-of-bounds write may corrupt kernel memory or other critical data, leading to a compromise of confidentiality, integrity, or availability depending on how the write is leveraged. [1]

Mitigation

Samsung has released security updates to address this issue. Users should apply the latest firmware updates from Samsung or their device manufacturer. The exact fixed version numbers are not provided in the reference, but the advisory directs users to the Samsung Mobile product security update page for details. [1]
