In the Linux kernel, the following vulnerability has been resolved:
can: etases58x: es58xrxerrmsg(): fix memory leak in error path
In es58xrxerrmsg(), if can->dosetmode() fails, the function directly returns without calling netifrx(skb). This means that the skb previously allocated by alloccanerr_skb() is not freed. In other terms, this is a memory leak.
This patch simply removes the return statement in the error branch and let the function continue.
Issue was found with GCC -fanalyzer, please follow the link below for details.
