Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: media: bcm2835-unicam: Fix asc leaked in error/remove path v4l2_async_nf_add_fwnode_remote() allocates the asc, which is freed when v4l2_async_nf_cleanup() is called. Call v4l2_async_nf_cleanup() properly in the driver paths.
