by ·

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

net: davicom: fix UAF in dm9000_drv_remove

dm is netdev private data and it cannot be
used after free_netdev() call. Using dm after free_netdev()
can cause UAF bug. Fix it by moving free_netdev() at the end of the
function.

This is similar to the issue fixed in commit
ad297cd2db89 (“net: qcom/emac: fix UAF in emac_remove”).

This bug is detected by our static analysis tool.
