Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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.
