- Details
-
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.
