CVE-2024-49896 is a medium severity vulnerability in the Linux kernel's AMD GPU display driver (amdgpu_dm). The issue arises because the driver can pass a null stream pointer to the function dc_is_stream_unchanged without checking for null, leading to a potential null pointer dereference. This flaw was identified and fixed by adding a null check before dereferencing the stream pointer, resolving a forward null pointer dereference issue.
