Description SMASH SMASH 2024-05-20 15:31:37 UTC

In the Linux kernel, the following vulnerability has been resolved:

net: bcmasp: fix memory leak when bringing down interface

When bringing down the TX rings we flush the rings but forget to
reclaimed the flushed packets. This leads to a memory leak since we
do not free the dma mapped buffers. This also leads to tx control
block corruption when bringing down the interface for power
management.
