An attacker, with low-level privileges and user interaction, can send a maliciously crafted payload to the GPU. The GPU, failing to correctly identify the type of the incoming data, tries to process it, leading to a Denial of Service condition. This can potentially compromise the system and lead to data leakage.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-2562708753\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Here is a<br \/>\n<strong>conceptual<\/strong><br \/>\n example of how the vulnerability might be exploited. This hypothetical shell command represents a malicious payload causing the type confusion:<\/p>\n<pre><code class=\"\" data-line=\"\">$ echo &quot;{ &#039;type&#039;: &#039;GPU_Process&#039;, &#039;data&#039;: &#039;malicious_payload&#039; }&quot; &gt; \/dev\/exynos_gpu<\/code><\/pre>\n<p>In this example, the attacker is echoing a JSON string into the Exynos GPU device file. The &#8216;type&#8217; field is set to &#8216;GPU_Process&#8217;, but the &#8216;data&#8217; field contains a malicious payload that the GPU cannot correctly process, leading to a Denial of Service.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview The vulnerability, identified as CVE-2024-49196, is a serious issue discovered in the GPU of Samsung Mobile Processor Exynos 1480 and 2400.
