CVE-2025-37872 Information

Description

In the Linux kernel the following vulnerability has been resolved:

net: txgbe: fix memory leak in txgbe_probe() error path

When txgbe_sw_init() is called memory is allocated for wx->rss_key in wx_init_rss_key(). However in txgbe_probe() function the subsequent error paths after txgbe_sw_init() don’t free the rss_key. Fix that by freeing it in error path along with wx->mac_table.

Also change the label to which execution jumps when txgbe_sw_init() fails because otherwise it could lead to a double free for rss_key when the mac_table allocation fails in wx_sw_init().
