Description OSIDB Bzimport 2025-12-24 14:05:32 UTC 
In the Linux kernel, the following vulnerability has been resolved:

media: platform: mtk-mdp3: Add missing check and free for ida_alloc

Add the check for the return value of the ida_alloc in order to avoid
NULL pointer dereference.
Moreover, free allocated "ctx->id" if mdp_m2m_open fails later in order
to avoid memory leak.
