&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;media: v4l2-mem2mem: add lock to protect parameter num_rdy&lt;/p&gt;
&lt;p&gt;Getting below error when using KCSAN to check the driver. Adding lock to
protect parameter num_rdy when getting the value with function:
v4l2_m2m_num_src_bufs_ready/v4l2_m2m_num_dst_bufs_ready.&lt;/p&gt;
